In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7770 VTX3D X-Edition are significantly better than the AMD Radeon HD 7750 1GB GDDR5.

The HD 7770 has a 350 MHz higher core clock speed and 8 more Texture Mapping Units than the HD 7750. This results in the HD 7770 providing 20.4 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 HD 7770 has a 350 MHz higher core clock speed than the HD 7750 and the same number of Render Output Units. This results in the HD 7770 providing 5.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7770 was released less than a year after the HD 7750, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 7770 VTX3D X-Edition and the Radeon HD 7750 1GB GDDR5 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 7770 has 8 GB/sec greater memory bandwidth than the HD 7750, which means that the memory performance of the HD 7770 is marginally better than the HD 7750.

The Radeon HD 7770 VTX3D X-Edition has 640 Shader Processing Units and the Radeon HD 7750 1GB GDDR5 has 512. However, the actual shader performance of the HD 7770 is 626 and the actual shader performance of the HD 7750 is 348. The HD 7770 having 278 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7770 delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 7750.

The Radeon HD 7750 1GB GDDR5 requires 55 Watts to run but there is no entry for the HD 7770. We would recommend a PSU with at least 450 Watts for the HD 7770 and a PSU with at least 400 Watts for the HD 7750. The HD 7770 has been recommended a PSU with 50 Watts more than the HD 7750. The difference is significant enough that the HD 7770 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 7750.

GPU Mini Review

Mini ReviewRadeon HD 7770 VTX3D X-Edition is a special edition of the fast-middle-class Radeon HD 7770. See the page of the standard version for more information about it.
It comes with overclocking out of the box in the core-clock that was raised from 1000MHz to 1150MHz and in the memory clock from 1125MHz to 1250MHz.
Expect a 11% performance boost when compared to the standard Radeon HD 7770.
Overview
Radeon HD 7750 is a Fast-Middle-Class Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.

Architecture
The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.

GPU
It equips a GPU Codenamed Cape Verde PRO which has 8 Compute Units activated and thus offers 512 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 800MHz.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1125MHz.

Power Consumption
With a rated board TDP of 55W, it requires at least a 400W PSU and relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Radeon HD 7750 competes with GeForce GTX 650 Ti but its performance was slightly behind it.

System Suggestions
Radeon HD 7750 is best suited for resolutions up to and including 1600x900. We recommend a Decent Processor (Intel Core i3 Quad Core/AMD FX Quad Core) and 8GB of RAM for Optimal Performance.
