However it is important to note that 7200 series does not support Scalable Link Interface.

GeForce 7200 GS

The 7200 GS has the same memory speed as the 7300 GS, and the core frequency is the same as the 7300 LE. It has two pixel pipelines. Nvidia stated that the 7200 GS performance is 50% higher than the latest integrated graphics, it's the slowest card of the GeForce 7 series and of the GeForce 6 Series but supports HDR and Nvidia PureVideo. NVIDIA GeForce 7200 GS desktop Graphics Processing Unit was launched in January 2006. The GPU uses Second Generation CineFX Shading architecture, and it is manufactured on 90 nm technological process. The card's graphics frequency is 450 MHz. It also has 2 pixel shaders, 4 texture units, together with 2 ROPs. The GeForce 7200 GS embeds 256 MB of DDR2 memory, utilizing 64 bit bus. The memory is clocked at 400 MHz, which results in 6.4 GB/s memory bandwidth. The GPU supports PCI Express 1.0 interface, and needs a single motherboard slot.

GeForce 7300 series

Nvidia designed the 7300 series to be entry level gaming video cards. Four models were available: the 7300 GT, the 7300 GS, the 7300 LE, and the 7300 SE.
This series was released to replace the older Geforce 6200 series.
;Features
In addition to the standard GeForce 7 series features, the 7300 series supports following advanced features:
The 7300 SE uses the same core frequency and memory speed as the 7300 LE, and has two vertex and pixel shaders. In many ways, this card is actually inferior to the 7100 GS, although it still retains the HDR support.

GeForce 7300 LE

The 7300 LE is a scaled-down version of the 7300 GS. It has DDR2 memory, and a slightly lower core clock speed. It is only available in the PCI Express interface. ASUS have produced a 7300 series card based on the 7300 LE core, running it at 580 MHz rather than 450 MHz.

GeForce 7300 GS

The 7300 GS the highest core clock speed of the 7300 series, thus it has better performance than the 7300 SE/LE.

GeForce 7300 GT

The 7300 GT has a 128-bit memory interface and the highest memory bandwidth, but slightly lower 3D vertex rendering.

GeForce 7500 series

The 7500 series was only available to OEMs.

GeForce 7500 ti super

The GeForce 7500 LE is an OEM GPU and is identical to the 7300 GS based on the G72 core. It has either 128 MB or 256 MB of dedicated video memory, however it also supports TurboCache, giving it up to 512 MB of video memory. It has DDR2 type memory and uses 64-bits memory interface. The card also has 550 MHz core clock speed and 263 MHz or 324 MHz memory clock speed.

    GeForce 7600 GS

On March 22, 2006, Nvidia announced the immediate availability of the GeForce 7600 GS GPU targeted at the low-mid end. This new GPU assumed the place of the GeForce 6600 GT, which had been around for some time.
The AGP version was introduced on July 21, 2006. According to Nvidia, this card is identical to the PCI-e version other than the interface. In addition, the AGP version uses Nvidia's AGP-PCIe bridge chip.
Preliminary testing showed that the GeForce 7600 GS outperforms a GeForce 6600 GT and ATI's counterpart, the ATI Radeon X1600 Pro.

GeForce 7600 GT

The 7600 GT is the high-mid range product in the 7 Series family.
The 7600 GT contains all the features of the GeForce 7 family. It was made to provide a GeForce 7 series card to the mass market; some companies released AGP versions. It incorporates DDR3 memory.

GeForce 7650 series

Much like the 7500 series, the 7650 GS was only available to OEMs.

GeForce 7650 GS (OEM)

The GeForce 7650GS was limited to a few OEM cards only. Not much is known about this card, other than that it uses the 80 nm process and uses DDR2 memory, with examples having 256MB of DDR2 ram.

GeForce 7800 series

The 7800 series was designed to deliver exceptional performance and was targeted towards the high-end market segment. This series was discontinued and replaced with the 7900 series in early 2006.
A total of 4 models were available: GeForce 7800 GTX 512, GeForce 7800 GTX, GeForce 7800 GT, and GeForce 7800 GS.
;Features
In addition to the standard GeForce 7 series features, the 7800 series supports following advanced features:
  • High dynamic range rendering
  • UltraShadow II
  • CineFX 4.0 Engine

    GeForce 7800 GT

The GeForce 7800 GT is the second GPU in the series, launched on August 11, 2005 with immediate retail availability. It has 20 pixel pipelines, 7 vertex shaders, 16 ROPs and a 400 MHz core clock, 500 MHz memory clock using GDDR3 memory.
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.

GeForce 7800 GS AGP

On February 2, 2006, Nvidia announced the 7800 GS as the first AGP 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 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.

GeForce 7800 GTX

The GeForce 7800 GTX was the first GPU 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, along with 24 pixel and 8 vertex shaders. It was succeeded by the 7900 GTX on March 9, 2006.
The PlayStation 3's Reality Synthesizer is based on the 256 MB model of the 7800 GTX, but with slight modifications.
