In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7750 1GB GDDR5 are marginally better than the AMD Radeon HD 4850 Gigabyte 512MB Edition.

The HD 7750 has a 160 MHz higher core clock speed than the HD 4850, but both GPUs exhibit the same Texture Fill Rate. 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 160 MHz higher core clock speed than the HD 4850 and the same number of Render Output Units. This results in the HD 7750 providing 2.6 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 7750 was released less than a year after the HD 4850, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 7750 has 512 MB more video memory than the HD 4850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7750 also has superior memory performance overall.

The HD 7750 has 11.8 GB/sec greater memory bandwidth than the HD 4850, which means that the memory performance of the HD 7750 is slightly better than the HD 4850.

The Radeon HD 4850 Gigabyte 512MB Edition has 800 Shader Processing Units and the Radeon HD 7750 1GB GDDR5 has 512. However, the actual shader performance of the HD 4850 is 358 and the actual shader performance of the HD 7750 is 348. The HD 4850 having 10 better shader performance is not particularly notable, as altogether the HD 7750 performs better when taking into account other relevant data.

The HD 7750 transistor size technology is 27 nm (nanometers) smaller than the HD 4850. This means that the HD 7750 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4850. While they exhibit similar graphical performance, the HD 7750 should consume less power than the HD 4850.

The Radeon HD 4850 Gigabyte 512MB Edition requires 110 Watts to run and the Radeon HD 7750 1GB GDDR5 requires 55 Watts. We would recommend a PSU with at least 450 Watts for the HD 4850 and a PSU with at least 400 Watts for the HD 7750. The HD 4850 requires 55 Watts more than the HD 7750 to run. The difference is significant enough that the HD 4850 may have an adverse affect on your yearly electricity bills in comparison to the HD 7750.

GPU Mini Review

Mini ReviewRadeon HD 4850 Gigabyte 512MB Edition is a special edition of the high-end Radeon HD 4850.
The new features include an increase in the central unit that went from 625MHz to 640MHz, while the operating memory clock was reduced to 940MHz. A new cooling system is also available.
The performance ends up being exactly like the reference card.
Radeon HD 7750 is a Fast-Middle-Class Graphics Card based on the First Revision of the Graphics Core Next (GCN) 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.

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.

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.

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.
