In terms of overall gaming performance, the graphical capabilities of the Nvidia Quadro K620 are marginally better than the AMD Radeon HD 6670 v2 MSI 2GB Edition.

The HD 6670 has a 133 MHz higher core clock speed than the Quadro K620, but the Quadro K620 has 8 more Texture Mapping Units than the HD 6670. As a result, the Quadro K620 exhibits a 2.1 GTexel/s better Texture Fill Rate than the HD 6670. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 6670 has a 133 MHz higher core clock speed than the Quadro K620, but the Quadro K620 has 8 more Render Output Units than the HD 6670. As a result, the Quadro K620 exhibits a 4.3 GPixel/s better Pixel Fill Rate than the HD 6670. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Quadro K620 was released over three years more recently than the HD 6670, and so the Quadro K620 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 6670 when running the latest games.

The HD 6670 has 1024 MB more video memory than the Quadro K620, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the Quadro K620 has superior memory performance.

The Quadro K620 has 7.5 GB/sec greater memory bandwidth than the HD 6670, which means that the memory performance of the Quadro K620 is marginally better than the HD 6670.

The Radeon HD 6670 v2 MSI 2GB Edition has 480 Shader Processing Units and the Quadro K620 has 384. However, the actual shader performance of the HD 6670 is 192 and the actual shader performance of the Quadro K620 is 346. The Quadro K620 having 154 better shader performance and an altogether better performance when taking into account other relevant data means that the Quadro K620 delivers a marginally smoother and more efficient experience when processing graphical data than the HD 6670.

The Quadro K620 transistor size technology is 12 nm (nanometers) smaller than the HD 6670. This means that the Quadro K620 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6670. While they exhibit similar graphical performance, the Quadro K620 should consume less power than the HD 6670.

The Radeon HD 6670 v2 MSI 2GB Edition requires 66 Watts to run and the Quadro K620 requires 45 Watts. We would recommend a PSU with at least 400 Watts for the HD 6670 and a PSU with at least 350 Watts for the Quadro K620. The HD 6670 requires 21 Watts more than the Quadro K620 to run. The difference is not significant enough for the HD 6670 to have a noticeably larger impact on your yearly electricity bills than the Quadro K620.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6670 v2 MSI 2GB Edition is a special edition of AMD's fast-middle-class Radeon HD 6670 v2, created by MSI.

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

Overclock: Memory Clock
The Operating Memory Clock runs at 667MHz and the Frame Buffer was raised to 2GB. 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, Radeon HD 6670 v2 MSI 2GB Edition is as fast as the reference Radeon HD 6670 v2.
Quadro K620 is a middle-class professional card based on the 28nm, Maxwell architecture.

It's based on the Maxwell GM107 GPU and offers 384 Shader Processing Units, 32 TMUs and 16 ROPs, on a 128-bit memory interface of standard DDR3. The central unit runs at 667MHz and the memory clock operates at up to 900MHz. It has a L2 Cache of 2048KB and a rated board TDP of 45 Watts.

Quadro K620's drivers are certified for professional applications only. Its gaming performance is about 30% above GeForce GT 720.
