In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 250 Gigabyte OC 1GB Edition are marginally better than the AMD Radeon HD 7750 VTX3D 1GB DDR3 Edition.

The R7 250 has a 250 MHz higher core clock speed than the HD 7750, but the HD 7750 has 8 more Texture Mapping Units than the R7 250. As a result, the HD 7750 exhibits a 0.4 GTexel/s better Texture Fill Rate than the R7 250. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R7 250 has a 250 MHz higher core clock speed than the HD 7750, but the HD 7750 has 8 more Render Output Units than the R7 250. As a result, the HD 7750 exhibits a 4.4 GPixel/s better Pixel Fill Rate than the R7 250. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R7 250 was released over a year more recently than the HD 7750, and so the R7 250 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 Radeon R7 250 Gigabyte OC 1GB Edition and the Radeon HD 7750 VTX3D 1GB DDR3 Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The R7 250 has 48 GB/sec greater memory bandwidth than the HD 7750, which means that the memory performance of the R7 250 is noticeably better than the HD 7750.

The Radeon R7 250 Gigabyte OC 1GB Edition has 384 Shader Processing Units and the Radeon HD 7750 VTX3D 1GB DDR3 Edition has 512. However, the actual shader performance of the R7 250 is 359 and the actual shader performance of the HD 7750 is 348. The R7 250 having 11 better shader performance and an altogether better performance when taking into account other relevant data means that the R7 250 delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 7750.

The Radeon R7 250 Gigabyte OC 1GB Edition requires 65 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 400 Watts for the R7 250 and a PSU with at least 400 Watts for the HD 7750. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewRadeon R7 250 Gigabyte OC 1GB Edition is a special edition of the middle-class Radeon R7 250 1GB.
This edition comes with a special 10cnm fan, which will reduce the card's temperature and comes overclocked out of the box in the central unit that was increased from 1000MHz to 1050MHz, while the Boost clock is now of 1100MHz.
Benchmarks indicate a 3% performance boost over the standard edition.
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.
