The GeForce 7800 GT had been introduced as a more affordable alternative to the 7800 GTX. At the time it was considered the performance/cost champion of video cards.
video card in the GeForce 7 series lineup, an AGP version of the high-end GeForce 7 Series.
This card was promoted by several hardware enthusiasts as "the last high-ended AGP card in existence". It has 16 pixel shader units instead of the 20 that the 7800 GT has, but still benefits from the optimizations of the other 7-series GPUs enjoy. Clock speeds are 375 MHz for the GPU
and 1200 MHz for the (GDDR3) memory. According to all benchmark tests, the performance of this card is faster than the GeForce 6800 GT and GeForce 6800 Ultra. Different vendors may deviate from the stated specification. It serves to provide a great upgrade path for those with high-end AGP systems who don't want to switch to a new high-end PCI-Express system.
There was a special "Golden Sample" release from Gainward that was called "7800 GS+" or officially "Bliss 7800 GS 512 MB GS+" that had default clock speeds of 450 MHz core and 1250 MHz memory. Unlike a standard 7800 GS, the 7800 GS+ actually used a 7900 GT GPU that had the full 24 pixel shaders instead of the regular 16 pixel shaders that are normally found on a 7800 GS video card.
Gainward had previously released a "Bliss 7800 GS 512MB GS" card that was based on a 7800 GT but utilized the AGP bus. Its external appearance and name make it nearly indistinguishable from the 7900 GT-based Bliss 7800 GS 512MB GS+. Leadtek produced a similar card with 256MB memory.
In late 2006 Gainward released a third '7800 GS' card with 20 pixel shaders running at 500 MHz core and 1400 MHz memory called the "BLISS GS-GLH". This card is also based on the 7900 GS core.
There are no after-market cooling systems for the 7800 GS, stock cooling in the GeForce 7800 GS AGP is adequate. The board layout is radically different from other GeForce 7 boards so no universal aftermarket coolers would fit without significant modification to their mounting mechanisms.
in the series, launched on June 22, 2005 with immediate retail availability. The GeForce 7800 GTX supported the highest specification DirectX 9 vertex and pixel shaders, at the time: Version 3.0. It was natively a PCI Express
chip. SLI
support had been retained and improved from the previous generation.
According to PC World
, the 7800 GTX was "one of the most complex processors ever designed". The GPU had 302 million transistors (the Athlon 64 X2
4800+ CPU has 233.2 million transistors), along with 24 pixel and 8 vertex shaders. It was succeeded by the 7900 GTX on March 9, 2006.
Performance Specs:
Nvidia's 7900 series is a product refresh and not a new generation of Nvidia's GPU, running at 650 MHz. Officially this series is meant to support only PCI Express Interface but some companies released AGP versions.
A total of 5 models have been developed and are available: 7900 GX2, 7900 GTX, 7900 GT, 7900 GTO and 7900 GS.
Features
In addition to the standard GeForce 7 Series features, the 7900 series supports following advanced features:
of US$199, the 7900 GS filled the gap between the mid-end GeForce 7600 GT and the high-end GeForce 7900 GT. The card was unofficially launched August 23 by woot!
as a white box OEM
. However, the product's company, MSI, made claims that these cards were stolen from MSI during transportation and sold to woot!
. The referenced MSI customer notice has been changed to remove explicit references to woot!. As of March 2007, Nvidia had discontinued production of a number of GeForce 6 and 7 series products, including the 7900 GS.
The GeForce 7900 GS has 20 pixel processors, 7 vertex processors, 256-bits memory bus, and comes clocked at approximately 450 MHz/1320 MHz for core/memory, which should provide slightly lower performance than the 7900 GT. The GeForce 7900 GS is powered by the latest graphics chip code-named G71, thus, shares the same advantages as the G71 did over its immediate predecessor G70: dual-link DVI outputs, reduced power consumption, higher performance.

support, had underclocked memory running at 1320 MHz, and used tighter memory timings. Other than that, the two boards were identical: same PCB, same cooler, same GPU. The GTO used extremely fast 1.1ns Samsung BJ11 GDDR3 memory running at 1.8V, as opposed to the 2.1V it is rated at. Clock speeds on the two cards are identical, at 650 MHz. At stock memory speeds, most comparisons found the GTO to lag behind the GTX by roughly a 5-10% margin.
The majority of owners find that their GTO will overclock to 1600 MHz memory speeds, despite the under-volted RAM. Many flash their GTO to a GTX BIOS to officially make it a GTX. GTO owners having trouble reaching GTX speeds with BIOS version 5.71.22.39.13 or newer are advised to simply flash to an older BIOS version such as 5.71.22.39.08, this seems to solve overclocking problems for most users.
The GTO was an extremely popular card among enthusiasts as it offered near GTX performance at a considerably lower price. It was a limited production card aimed at cleaning out G70 inventories before the release of the G80, and only spent about a month in retail channels before selling out.
Dual GeForce 7800 GT or nVidia's own 7950 GX2, where two GPUs are on the same card. This enables quad-SLI on two PCI Express x16
slots. Other OEM companies have access to the GX2 and it is now available from numerous vendors.
The card features a 500 MHz GPU and 1200 MHz effective RAM speed. Although the power of the GX2 is less than the 7900 GTX, each card is more powerful than the 7900 GT.
Many issues in this implementation of a dual-GPU unit convinced Nvidia to restrict its sale to OEM companies. The card is extremely long, with only the largest e-ATX
case
s being able to hold it. Two of the cards operating in quad-SLI
also required extremely well designed airflow to function, and demanded a 1000 watt
power supply unit.
Two models are available: 7950 GT and 7950 GX2.
Features
In addition to the standard GeForce 7 Series features, the 7950 series supports following advanced features:
Performance Specs:
NOTE: XFX has developed and released AGP versions of this card.
The 7950 GX2 was released to retail on June 5, 2006, and shares similar specs to the GeForce 7900 GX2, with 500 MHz GPU clock, and 1200 MHz effective RAM speed. 512 MB of memory per GPU, for a total of 1 GB, however total performance is more in line with 512 MB since each GPU can only access its own memory and not the memory of the other one. It does not offer any advantages over single-GPU cards with 512 MB, memory wise.
This card is designed for the DIY market; it addresses many problems which the previous 7900 GX2 had suffered from, such as noise, size, power consumption, and price. The 7950 GX2 requires only a single PCIe power connector, in contrast to the twin-connectors of its predecessor; technically, this is understandable, as there is no need for a ring bus configuration – frames need only be passed on to the primary GPU. It is much shorter, fitting easily in the same space as a 7900 GTX. Lesser board layout and the removal of cooling vents on the bracket have greatly declined cooling, allowing the fans to run at a lower speed, thereby lowering noise. As of September 2006, the board can be found for $299, half the cost of a 7900 GX2.
According to some review sites (such as Tom's Hardware - see above), a single 7950GX2 draws less power than a single ATI Radeon X1900 XT – some consider this an amazing feat considering the GX2 employs a pair of GPUs, when the Radeon uses only one. Other review sites say that a GX2 is quieter than the aforementioned Radeon, despite the GX2 boasting a pair of identical GPU coolers – however 'loudness' is highly subjective without the proper tools and testing conditions. If true, this would make a pair of GX2 cards cooler, quieter, and less power hungry than a pair of X1900 XT cards in CrossFire. However, there is no appreciable performance gain from pairing two 7950 GX2 cards in most applications, while dual X1900 XT configurations see large performance boosts in CrossFire mode.
Performance Specs:
On August 9, 2006, Nvidia released initial ForceWare 91.45 drivers for Windows 2000 and XP that support Quad SLI. The Quad SLI support was soon merged in with the normal WHQL driver package, when ForceWare 91.47 drivers was released on October 16, 2006.

GeForce 7800 GTX 512
The 512 MB version of the GeForce 7800 GTX was released on November 14, 2005. The card features more than simply an increased frame buffer from 256 MB to 512 MB. The card features a much improved core clock speed of 550 MHz vs. 430 MHz (27.9% increase) and fast 1.1 ns GDDR3 memory clocked at 1.7 GHz vs. 1.2 GHz (41.7% increase), when compared to the original version. Like ATI's X1800 XT, the addition of another 256 MB of memory, and to a lesser extent, the increased clock speeds, have raised the heat and power output significantly. To combat this, the GeForce 7800 GTX 512 sports a much larger yet quieter dual slot cooling solution when compared to the original 256 MB version.Performance Specs:
- Core Clock Speed: 550 MHz
- Memory Interface: 256-bits
- Memory Bandwidth: 54.4 GB/s
- Fill Rate: 8.8 billion pixel/s, 13.2 billion texel/s
- Vertex/s: 1100 millions
- Shader Power: 24 pixels per clock
- Memory Type: GDDR3

. The referenced MSI customer notice has been changed to remove explicit references to woot!. As of March 2007, Nvidia had discontinued production of a number of GeForce 6 and 7 series products, including the 7900 GS.
The GeForce 7900 GS has 20 pixel processors, 7 vertex processors, 256-bits memory bus, and comes clocked at approximately 450 MHz/1320 MHz for core/memory, which should provide slightly lower performance than the 7900 GT. The GeForce 7900 GS is powered by the latest graphics chip code-named G71, thus, shares the same advantages as the G71 did over its immediate predecessor G70: dual-link DVI outputs, reduced power consumption, higher performance.

GeForce 7900 GTX
The GeForce 7900 GTX is a 90 nm produced G70 (named G71) and features all the same features of the 7800 GTX but is built upon the smaller manufacturing process. Due to shortages of memory modules for the 512 MB GTX, more readily available 1600 MHz memory was used.Performance Specs:
- Core Clock Speed: 650 MHz
- Memory Interface: 256-bits
- Memory Bandwidth: 51.2 GB/s memory bandwidth
- Fill Rate: 15.6 Billion pixel/s
- Vertex/s: 1.4 Billion

GeForce 7900 GTO
The 7900 GTO is a close cousin of the 7900 GTX. The GTO first arrived at a handful of retailers around October 1, 2006. At the time of launch, GTO boards sold for around US$250, compared to the 7900 GTX boards that cost in excess of $400 at the time. The GTO was essentially identical to the GTX, with the exception that it lacked HDCPHigh-Bandwidth Digital Content Protection

support, had underclocked memory running at 1320 MHz, and used tighter memory timings. Other than that, the two boards were identical: same PCB, same cooler, same GPU. The GTO used extremely fast 1.1ns Samsung BJ11 GDDR3 memory running at 1.8V, as opposed to the 2.1V it is rated at. Clock speeds on the two cards are identical, at 650 MHz. At stock memory speeds, most comparisons found the GTO to lag behind the GTX by roughly a 5-10% margin.
The majority of owners find that their GTO will overclock to 1600 MHz memory speeds, despite the under-volted RAM. Many flash their GTO to a GTX BIOS to officially make it a GTX. GTO owners having trouble reaching GTX speeds with BIOS version 5.71.22.39.13 or newer are advised to simply flash to an older BIOS version such as 5.71.22.39.08, this seems to solve overclocking problems for most users.
The GTO was an extremely popular card among enthusiasts as it offered near GTX performance at a considerably lower price. It was a limited production card aimed at cleaning out G70 inventories before the release of the G80, and only spent about a month in retail channels before selling out.

GeForce 7950 GT
On 14 September 2006 Nvidia released the 7950GT. Announced with a 550 MHz core clock, 700 MHz (1400 MHz effective) memory clock, 24 pixel shader units, standard configurations come equipped with both 512 MB GDDR3 memory and HDCP support. At an introductory price of US$300, the GeForce 7950 GT replaces the older GeForce 7900 GT and improves performance: the GeForce 7950 GT has a fillrate of 13,200 Megatexels/s and a memory bandwidth of 44.8 GB/s (versus 10800 Megatexels/s and 940 Megavertices/s for the 7900 GT).Performance Specs:
- Memory Interface: 256-bits
- Memory Bandwidth: 44.8 GB/s memory bandwidth
- Fill Rate: 13.2 Billion pixel/s
- Vertex/s: 1.1 Billion
- Shader Power: 24 pixels per clock
- SLI Support (PCI-E model only)
- Memory Type: GDDR3
NOTE: XFX has developed and released AGP versions of this card.
GeForce 7950 GX2
This is essentially a dual-GPU video card that takes up only a single PCIe x16 slot, allowing for 4 GPUs to run with only two PCIe x16 slots, in standard SLI motherboards. Unlike the 7900 GX2 before it, this version is available to consumers directly.The 7950 GX2 was released to retail on June 5, 2006, and shares similar specs to the GeForce 7900 GX2, with 500 MHz GPU clock, and 1200 MHz effective RAM speed. 512 MB of memory per GPU, for a total of 1 GB, however total performance is more in line with 512 MB since each GPU can only access its own memory and not the memory of the other one. It does not offer any advantages over single-GPU cards with 512 MB, memory wise.
This card is designed for the DIY market; it addresses many problems which the previous 7900 GX2 had suffered from, such as noise, size, power consumption, and price. The 7950 GX2 requires only a single PCIe power connector, in contrast to the twin-connectors of its predecessor; technically, this is understandable, as there is no need for a ring bus configuration – frames need only be passed on to the primary GPU. It is much shorter, fitting easily in the same space as a 7900 GTX. Lesser board layout and the removal of cooling vents on the bracket have greatly declined cooling, allowing the fans to run at a lower speed, thereby lowering noise. As of September 2006, the board can be found for $299, half the cost of a 7900 GX2.
According to some review sites (such as Tom's Hardware - see above), a single 7950GX2 draws less power than a single ATI Radeon X1900 XT – some consider this an amazing feat considering the GX2 employs a pair of GPUs, when the Radeon uses only one. Other review sites say that a GX2 is quieter than the aforementioned Radeon, despite the GX2 boasting a pair of identical GPU coolers – however 'loudness' is highly subjective without the proper tools and testing conditions. If true, this would make a pair of GX2 cards cooler, quieter, and less power hungry than a pair of X1900 XT cards in CrossFire. However, there is no appreciable performance gain from pairing two 7950 GX2 cards in most applications, while dual X1900 XT configurations see large performance boosts in CrossFire mode.
Performance Specs:
- Memory Interface: 2x 256-bits

- Memory Type: GDDR3
On August 9, 2006, Nvidia released initial ForceWare 91.45 drivers for Windows 2000 and XP that support Quad SLI. The Quad SLI support was soon merged in with the normal WHQL driver package, when ForceWare 91.47 drivers was released on October 16, 2006.
