In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 650 Ti Power Edition OC 1GB are significantly better than the AMD Radeon HD 4870.

The GTX 650 Ti has a 243 MHz higher core clock speed and 24 more Texture Mapping Units than the Radeon HD 4870. This results in the GTX 650 Ti providing 33.6 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 650 Ti has a 243 MHz higher core clock speed than the Radeon HD 4870 and the same number of Render Output Units. This results in the GTX 650 Ti providing 3.9 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 650 Ti was released over three years more recently than the Radeon HD 4870, and so the GTX 650 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 650 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 28.8 GB/sec greater memory bandwidth than the GTX 650 Ti, which means that the memory performance of the Radeon HD 4870 is slightly better than the GTX 650 Ti.

The GeForce GTX 650 Ti Power Edition OC 1GB has 768 Shader Processing Units and the Radeon HD 4870 has 800. However, the actual shader performance of the GTX 650 Ti is 763 and the actual shader performance of the Radeon HD 4870 is 390. The GTX 650 Ti having 373 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 650 Ti delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon HD 4870.

The GTX 650 Ti transistor size technology is 27 nm (nanometers) smaller than the Radeon HD 4870. This means that the GTX 650 Ti is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 4870.

The Radeon HD 4870 requires 150 Watts to run but there is no entry for the GTX 650 Ti. We would recommend a PSU with at least 500 Watts for the Radeon HD 4870, but we do not have a recommended PSU wattage for the GTX 650 Ti.

GPU Mini Review

Mini ReviewGeForce GTX 650 Ti Power Edition OC 1GB is a special edition of the fast-middle-class GeForce GTX 650 Ti.
This edition features a new and better cooling system called Cyclone II Thermal Design with Dust Removal technology and an increase in the central clock that went from 928MHz to 993MHz. The Memory clock was left untouched.
The overclocking is relevant and benchmarks indicate there's a 4% boost when compared to the reference GeForce GTX 650 Ti.
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.
