Nvidia announced immediate availability of the GeForce 7600 series on March 9, 2006. Currently two Models are available and these are GeForce 7600 GT and 7600 GS.[6] This series is available with AGP and PCI-Express interfaces, covering a wide range of market segments.
This series was released to replace the older GeForce 6600 series.
Advanced Features Support:
The 7600 series supports following advanced features:
| Intellisample 4.0 Technology |
| Scalable Link Interface (SLI) Technology |
| Extreme HD Technology |
| High dynamic range rendering Technology |
| UltraShadow II Technology |
| CineFX 4.0 Engine |
| Nvidia PureVideo Technology |
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 quite some time.
The AGP version was introduced in 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.
Performance Specs:
- Core Clock Speed: 400 MHz core frequency
- Memory Clock Speed: 400 MHz (800 MHz effective)
- Memory Interface: 128-bit
- Memory Bandwidth: 12.8 GB/s
- Fill Rate: 3.2 billion pixel/s and 4.8 billion texel/s
- Vertex/s: 500 million
- SLI support (Only for the PCIe version)
- Cooling Solution: Passively cooled (Nvidia reference)
- Memory Type: GDDR3 or DDR-2
Preliminary testing showed that the GeForce 7600 GS outperforms a GeForce 6600 GT and ATI's counterpart, the ATI Radeon X1600 Pro.[7]
GeForce 7600 GT
This is the high-mid range product in the 7 Series family.
Performance Specs:
- Core Clock Speed: 560 MHz
- Memory Clock Speed: 700 MHz (1400 MHz effective)
- Memory Interface: 128-bit
- Memory Bandwidth: 22.4 GB/s memory bandwidth
- Fill Rate:4.48 billion pixel/s and 6.72 billion texel/s
- Vertex/s: 700 million
- SLI Support (for PCI-E Model)
- Shader Power: 12 pixels per cycle
- Memory Type: GDDR3 or DDR2
The 7600 contains all the features of the GeForce 7 family, and is priced rather low for the mainstream market. It was made to provide a Geforce 7 series card to the mass market. By using the same PCB and GPU socket as the 6600, manufacturing costs should be lower due to available parts left over; and the fact that it is built on a smaller wafer. When benchmarks revealed that the 7600 GT seriously outperformed its original market opponent, the ATI Radeon X1600 XT, ATI reduced prices of its Radeon X850XT PE (the fastest video card of its previous-generation product line) and introduced the X1800 GTO, which was slightly more expensive than the 7600 GT, but marginally faster thanks to its 256-bit memory bus, higher peak pixel fill rate and more raw shading power. However, the memory speeds in the 7600 GT are underclocked, leaving quite a lot of headroom for overclocking. Card manufacturer Leadtek introduced an AGP version of the card in August 2006, which was one of the few AGP cards in the market including the new, faster, GDDR3 memory.[8]
GeForce 7650 Series
GeForce 7650 GS
The GeForce 7650GS was never officially released, and was limited to a few OEM cards only. This card is seemingly very rare. Performance is speculated to be very similar to the 7600GS. Not much is known about this card, other than that it uses the 80 nm process.
Performance Specs:
These specifications are based on a card manufactured by Asus.[9] There might be differences between OEM cards.
- Core Clock Speed: 400 MHz core frequency
- Memory Clock Speed: 400 MHz (800 MHz effective)
- Memory Interface: 128-bit
- Memory Bandwidth: 12.8 GB/s
- Fill Rate: 3.6 GPixel/s and 5.4 GTexel/s
- Cooling Solution: Passively cooled
- Memory Type: DDR-2
A card manufactured by MSI gives the same specification, however it has a 5.4 GTexel/s rating.[10] This is caused by a bug in earlier versions of GPU-Z. Since version 0.2.0 the fillrate calculation on G73 chips is fixed, so even the card manufactured by ASUS would show the real 5.4 GTexel/s.
