In terms of overall gaming performance, the graphical capabilities of the AMD FirePro D300 are significantly better than the AMD Radeon HD 7750 VTX3D 1GB DDR3 Edition.

The HD 7750 has a 25 MHz higher core clock speed than the FirePro D300, but the FirePro D300 has 48 more Texture Mapping Units than the HD 7750. As a result, the FirePro D300 exhibits a 36.4 GTexel/s better Texture Fill Rate than the HD 7750. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7750 has a 25 MHz higher core clock speed than the FirePro D300, but the FirePro D300 has 16 more Render Output Units than the HD 7750. As a result, the FirePro D300 exhibits a 12 GPixel/s better Pixel Fill Rate than the HD 7750. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The FirePro D300 was released over a year more recently than the HD 7750, and so the FirePro D300 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7750.

The FirePro D300 has 1024 MB more video memory than the HD 7750, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the FirePro D300 also has superior memory performance overall.

The FirePro D300 has 134.4 GB/sec greater memory bandwidth than the HD 7750, which means that the memory performance of the FirePro D300 is massively better than the HD 7750.

The FirePro D300 has 1280 Shader Processing Units and the Radeon HD 7750 VTX3D 1GB DDR3 Edition has 512. However, the actual shader performance of the FirePro D300 is 645 and the actual shader performance of the HD 7750 is 348. The FirePro D300 having 297 better shader performance and an altogether better performance when taking into account other relevant data means that the FirePro D300 delivers a massively smoother and more efficient experience when processing graphical data than the HD 7750.

The FirePro D300 requires 150 Watts to run but there is no entry for the Radeon HD 7750 VTX3D 1GB DDR3 Edition. We would recommend a PSU with at least 500 Watts for the FirePro D300 and a PSU with at least 400 Watts for the HD 7750. The FirePro D300 has been recommended a PSU with 100 Watts more than the HD 7750. The difference is significant enough that the FirePro D300 may have an adverse affect on your yearly electricity bills in comparison to the HD 7750.

GPU Mini Review

Mini ReviewFirePro D300 is a workstation Graphics Card based on the 28nm GCN architecture.
It's based on the Pitcairn XT Core (same used on 7870) and therefore offers 1280 Shader Processing Units, 80 TMUs and 32 ROPs on a 256-bit interface of fast GDDR5. The central unit is clocked 775MHz while the memory clock operates at 1250MHZ.
It is thus considerably lower clocked and its gaming performance is even lower, as Radeon HD 7870 benefits from certified gaming drivers which unlock the GCN's architecture potential while FirePro D300 is made for professional applications. Therefore, expect its performance to be similar to Radeon HD 7850.
Radeon HD 7750 VTX3D 1GB DDR3 Edition is a special edition of the fast-middle-class Radeon HD 7750 1GB DDR3.
This version has no new features (when compared to the DDR3 version) and so it performs exactly like it.
