In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 4870 are marginally better than the Nvidia GeForce GTX 550 Ti WindForce Edition.

The GTX 550 Ti has a 220 MHz higher core clock speed but 8 fewer Texture Mapping Units than the Radeon HD 4870. The lower TMU count doesn't matter, though, as altogether the GTX 550 Ti manages to provide 1 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 550 Ti has a 220 MHz higher core clock speed and 8 more Render Output Units than the Radeon HD 4870. This results in the GTX 550 Ti providing 11.3 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 550 Ti was released over three years more recently than the Radeon HD 4870, and so the GTX 550 Ti is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon HD 4870 when running the latest games.

The GTX 550 Ti has 512 MB more video memory than the Radeon HD 4870, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The Radeon HD 4870 has 16.8 GB/sec greater memory bandwidth than the GTX 550 Ti, which means that the memory performance of the Radeon HD 4870 is slightly better than the GTX 550 Ti.

The GeForce GTX 550 Ti WindForce Edition has 192 Shader Processing Units and the Radeon HD 4870 has 800. However, the actual shader performance of the GTX 550 Ti is 372 and the actual shader performance of the Radeon HD 4870 is 390. The Radeon HD 4870 having 18 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 4870 delivers a marginally smoother and more efficient experience when processing graphical data than the GTX 550 Ti.

The GTX 550 Ti transistor size technology is 15 nm (nanometers) smaller than the Radeon HD 4870. This means that the GTX 550 Ti is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 4870. While they exhibit similar graphical performance, the GTX 550 Ti should consume less power than the Radeon HD 4870.

The Radeon HD 4870 requires 150 Watts to run but there is no entry for the GTX 550 Ti. We would recommend a PSU with at least 400 Watts for the GTX 550 Ti and a PSU with at least 500 Watts for the Radeon HD 4870. The Radeon HD 4870 has been recommended a PSU with 100 Watts more than the GTX 550 Ti. The difference is significant enough that the Radeon HD 4870 may have an adverse affect on your yearly electricity bills in comparison to the GTX 550 Ti.

GPU Mini Review

Mini ReviewGeForce GTX 550 Ti WindForce Edition is a special edition of the upper-middle-class GeForce GTX 550 Ti. See the standard edition's page for more information.
The new features include an increase in the clock from 900MHz to 970MHz and a new cooling system.
Benchmarks indicate a 4.5% performance boost when compared to the reference card..
Some modern demanding games will run at the highest settings using a 1080p resolution but the largest part will have to be played with a 720p resolution to be played optimally.
This Graphics Card needs to be paired with a decent Quad Core CPU.
Radeon HD 4870 is a high-end GPU based on the 55nm, third unified shader architecture, R700.
It's based on the RV770 PRO Core and offers 800 Shader Processing Units, 40 TMUs and 16 ROPs a 256-bit memory interface of fast GDDR5. The central unit runs at 750MHz and the memory clock runs at up to 900MHz.
Compared to Radeon HD 4890, it offers slightly less bandwidth (thanks to the higher operating memory clock), the central unit is lower clocked and features twice as less video memory. However, it only consumes up to 150W (40W less). The performance difference between is not very significant and so Radeon HD 4870 might be the best choice, over 4890 since it can be easily overclocked.
Most of today's modern games should run fluently at high settings but with modest resolutions. DirectX 11 games aren't supported.
