In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 770 EVGA 4GB Classified Edition SLI are significantly better than the AMD Radeon HD 8950 (OEM).

The GTX 770 has a 300 MHz higher core clock speed and 144 more Texture Mapping Units than the HD 8950. This results in the GTX 770 providing 199.2 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 GTX 770 has a 300 MHz higher core clock speed and 32 more Render Output Units than the HD 8950. This results in the GTX 770 providing 46.4 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 GTX 770 was released less than a year after the HD 8950, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GTX 770 has 3072 MB more video memory than the HD 8950, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 770 also has superior memory performance overall.

The GTX 770 has 208.8 GB/sec greater memory bandwidth than the HD 8950, which means that the memory performance of the GTX 770 is massively better than the HD 8950.

The GeForce GTX 770 EVGA 4GB Classified Edition SLI has 3072 Shader Processing Units and the Radeon HD 8950 (OEM) has 1792. However, the actual shader performance of the GTX 770 is 3693 and the actual shader performance of the HD 8950 is 1658. The GTX 770 having 2035 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 770 delivers a massively smoother and more efficient experience when processing graphical data than the HD 8950.

The GeForce GTX 770 EVGA 4GB Classified Edition SLI requires 400 Watts to run and the Radeon HD 8950 (OEM) requires 200 Watts. We would recommend a PSU with at least 750 Watts for the GTX 770 and a PSU with at least 500 Watts for the HD 8950. The GTX 770 requires 200 Watts more than the HD 8950 to run. The difference is significant enough that the GTX 770 may have an adverse affect on your yearly electricity bills in comparison to the HD 8950.

GPU Mini Review

Mini ReviewGeForce GTX 770 EVGA 4GB Classified Edition SLI is a combination of two GeForce GTX 770 EVGA 4GB Classified Edition put together using NVIDIA's SLI technology.Overview
Radeon HD 8950 (OEM) is an OEM Only, High-End Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.

Architecture
The GCN 1.1 revision of the Graphics Core Next Architecture adds new important technologies and is largely oriented for energy efficiency. New technologies such as PowerTune and TrueAudio are the biggest additions as well as DirectX 11.2 support.

GPU
It equips a GPU Codenamed Tahiti PRO2 which has 28 Compute Units activated and thus offers 1792 Shader Processing Units, 112 TMUs and 32 ROPs. The Central Unit is clocked at 850MHz and goes up to 925MHz, in Turbo Mode.

Memory
The GPU accesses a 3GB frame buffer of fast GDDR5, through a 384-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 1250MHz.

Power Consumption
With a rated board TDP of 200W, it requires at least a 500W PSU with two available 6-pin connectors.

Performance
Radeon HD 8950 (OEM) is a Direct Rebrand of Radeon HD 7950 Boost Edition and performs exactly like it.

System Suggestions
Radeon HD 8950 (OEM) is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor (Intel Core i5 Quad Core/AMD FX Six Core) and 8GB of RAM for Optimal Performance.
