In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8600 GT 512MB GDDR3 are very slightly better than the Nvidia GeForce GT 620 PNY PCIe 1GB Edition.

The GT 620 has a 160 MHz higher core clock speed and the same number of Texture Mapping Units as the 8600 GT. This results in the GT 620 providing 2.6 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 620 has a 160 MHz higher core clock speed than the 8600 GT, but the 8600 GT has 4 more Render Output Units than the GT 620. As a result, the 8600 GT exhibits a 1.5 GPixel/s better Pixel Fill Rate than the GT 620. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GT 620 was released over three years more recently than the 8600 GT, and so the GT 620 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 8600 GT when running the latest games.

The GT 620 has 512 MB more video memory than the 8600 GT, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the 8600 GT has superior memory performance.

The 8600 GT has 13.8 GB/sec greater memory bandwidth than the GT 620, which means that the memory performance of the 8600 GT is slightly better than the GT 620.

The GeForce GT 620 PNY PCIe 1GB Edition has 96 Shader Processing Units and the GeForce 8600 GT 512MB GDDR3 has 32. However, the actual shader performance of the GT 620 is 134 and the actual shader performance of the 8600 GT is 43. The GT 620 having 91 better shader performance is not particularly notable, as altogether the 8600 GT performs better when taking into account other relevant data.

The GT 620 transistor size technology is 40 nm (nanometers) smaller than the 8600 GT. This means that the GT 620 is expected to run much cooler and achieve higher clock frequencies than the 8600 GT. While they exhibit similar graphical performance, the GT 620 should consume less power than the 8600 GT.

The GeForce GT 620 PNY PCIe 1GB Edition requires 30 Watts to run and the GeForce 8600 GT 512MB GDDR3 requires 46 Watts. We would recommend a PSU with at least 300 Watts for the GT 620 and a PSU with at least 350 Watts for the 8600 GT. The 8600 GT requires 16 Watts more than the GT 620 to run. The difference is not significant enough for the 8600 GT to have a noticeably larger impact on your yearly electricity bills than the GT 620.

GPU Mini Review

Mini ReviewOverview
GeForce GT 620 PNY PCIe 1GB Edition is a special edition of NVIDIA's Entry-Level GeForce GT 620, created by PNY.

Overclock: Central Unit
The Central Unit runs at the same speed.

Overclock: Memory Clock
The Operating Memory Clock runs at 535MHz while the Frame Buffer remains the same: 1GB. This is a gimmick and in no way benefits the GPU.

Cooling Solution
The Cooling System remains the same.

Performance
Without Overclocking Out of The Box, GeForce GT 620 PNY PCIe 1GB Edition is as fast as the reference GeForce GT 620.
GeForce 8600 GT 512MB GDDR3 is one of the many variants of the fast-middle-class GeForce 8600 GT.
On this version, the GPU is equipped with 512MB of standard GDDR3. The architecture allows the use of 512MB, since the GPU's processing power is strong enough and the memory controller is up for the task of processing 512MB. Therefore, the performance is superior to the 256MB version and any other version of DDR2, including 1GB.
However, and due to its architecture limitations, modern demanding games will require reduced settings, even if they don't require more than 512MB of video ram. Very Demanding games like Metro 2033 are only playable at the lowest settings.
