In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 9800 GT 1GB SLI are marginally better than the Nvidia GeForce GTX 650 Gigabyte OC 1GB Edition.

The GTX 650 has a 510 MHz higher core clock speed than the 9800 GT, but the 9800 GT has 80 more Texture Mapping Units than the GTX 650. As a result, the 9800 GT exhibits a 31.7 GTexel/s better Texture Fill Rate than the GTX 650. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 650 has a 510 MHz higher core clock speed than the 9800 GT, but the 9800 GT has 16 more Render Output Units than the GTX 650. As a result, the 9800 GT exhibits a 1.4 GPixel/s better Pixel Fill Rate than the GTX 650. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 650 was released over three years more recently than the 9800 GT, and so the GTX 650 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 9800 GT when running the latest games.

The 9800 GT has 1024 MB more video memory than the GTX 650, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the 9800 GT also has superior memory performance overall.

The 9800 GT has 35.2 GB/sec greater memory bandwidth than the GTX 650, which means that the memory performance of the 9800 GT is noticeably better than the GTX 650.

The GeForce 9800 GT 1GB SLI has 224 Shader Processing Units and the GeForce GTX 650 Gigabyte OC 1GB Edition has 384. However, the actual shader performance of the 9800 GT is 336 and the actual shader performance of the GTX 650 is 426. The GTX 650 having 90 better shader performance is not particularly notable, as altogether the 9800 GT performs better when taking into account other relevant data.

The GTX 650 transistor size technology is 37 nm (nanometers) smaller than the 9800 GT. This means that the GTX 650 is expected to run much cooler and achieve higher clock frequencies than the 9800 GT. While they exhibit similar graphical performance, the GTX 650 should consume less power than the 9800 GT.

The GeForce 9800 GT 1GB SLI requires 200 Watts to run but there is no entry for the GeForce GTX 650 Gigabyte OC 1GB Edition. We would recommend a PSU with at least 500 Watts for the 9800 GT and a PSU with at least 400 Watts for the GTX 650. The 9800 GT has been recommended a PSU with 100 Watts more than the GTX 650. The difference is significant enough that the 9800 GT may have an adverse affect on your yearly electricity bills in comparison to the GTX 650.

GPU Mini Review

Mini ReviewOverview
GeForce 9800 GT 1GB SLI is a solution of two GeForce 9800 GT 1GB put together using NVIDIA's SLI Technology.

It consists of 2 GPUs Codenamed G92-270-A2 which, together, offer 224 Shader Processing Units, 112 TMUs and 32 ROPs. The central unit runs at 600MHz.

Each GPU accesses a 1GB frame buffer of GDDR3, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.

Power Consumption
Power Consumption lies between 190W and 220W.

System Suggestions
GGeForce 9800 GT 1GB SLI is best suited for resolutions up to and including 1600x900.
GeForce GTX 650 Gigabyte OC 1GB Edition is a special edition of the fast-middle-class GeForce GTX 650 1GB.
This special edition comes overclocked out of the box to 1110MHz and features a custom-designed 10 cm cooler.
Benchmarks indicate a 4% performance boost when compared to the reference card and so this GPU is suitable for medium to high settings on most demanding games but not with extreme resolutions.
