Game Radeon HD 5770 Sapphire Vapor-X Edition GeForce GTX 260

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 260 are marginally better than the AMD Radeon HD 5770 Sapphire Vapor-X Edition.

The HD 5770 has a 284 MHz higher core clock speed than the GeForce GTX 260, but the GeForce GTX 260 has 24 more Texture Mapping Units than the HD 5770. As a result, the GeForce GTX 260 exhibits a 2.5 GTexel/s better Texture Fill Rate than the HD 5770. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 5770 has a 284 MHz higher core clock speed than the GeForce GTX 260, but the GeForce GTX 260 has 12 more Render Output Units than the HD 5770. As a result, the GeForce GTX 260 exhibits a 2.3 GPixel/s better Pixel Fill Rate than the HD 5770. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 5770 was released over a year more recently than the GeForce GTX 260, and so the HD 5770 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GTX 260.

The HD 5770 has 128 MB more video memory than the GeForce GTX 260, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the HD 5770 also has superior memory performance overall.

The GeForce GTX 260 has 35.1 GB/sec greater memory bandwidth than the HD 5770, which means that the memory performance of the GeForce GTX 260 is noticeably better than the HD 5770.

The Radeon HD 5770 Sapphire Vapor-X Edition has 800 Shader Processing Units and the GeForce GTX 260 has 192. However, the actual shader performance of the HD 5770 is 344 and the actual shader performance of the GeForce GTX 260 is 254. The HD 5770 having 90 better shader performance is not particularly notable, as altogether the GeForce GTX 260 performs better when taking into account other relevant data.

The HD 5770 transistor size technology is 25 nm (nanometers) smaller than the GeForce GTX 260. This means that the HD 5770 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 260. While they exhibit similar graphical performance, the HD 5770 should consume less power than the GeForce GTX 260.

The Radeon HD 5770 Sapphire Vapor-X Edition requires 108 Watts to run and the GeForce GTX 260 requires 182 Watts. We would recommend a PSU with at least 500 Watts for the HD 5770 and a PSU with at least 500 Watts for the GeForce GTX 260. The GeForce GTX 260 requires 74 Watts more than the HD 5770 to run. The difference is significant enough that the GeForce GTX 260 may have an adverse affect on your yearly electricity bills in comparison to the HD 5770.

GPU Mini Review

Mini ReviewRadeon HD 5770 Sapphire Vapor-X Edition is a special edition of the Radeon HD 5770. See the page of the standard edition for more information about it.
Compared to the Radeon HD 5770, this Special Edition features overclocking out of the box in the core-clock which was increased by 10MHz to 860MHz and a new cooling system.
Unfortunately, benchmarks indicate the performance boost is below 1% when compared to the reference card.
Overview
GeForce GTX 260 is a Performance Graphics Card based on the Second Revision of the Tesla Architecture.

Architecture
Tesla was NVIDIA's First Unified Shader Architecture.

GPU
It equips a GPU Codenamed G200-100-A2 which has 8 Stream Multiprocessors activated and thus offers 192 Shader Processing Units, 64 TMUs and 28 ROPs. The Central Unit is clocked at 576MHz.

Memory
The GPU accesses a 896MB frame buffer of GDDR3, through a 448-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 999MHz.

Features
DirectX 10.0 Support (10.0 Hardware Default) and support for SLI, NVIDIA PureVideo HD Technology, Dual-stream Hardware Acceleration, PhysX, CUDA, HybridPower and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 182W, it requires at least a 500W PSU and it requires at least two 6-pin available connectors.

Performance
Gaming benchmarks put its performance around of a Radeon HD 4870, meaning it is much faster than GeForce GTS 250.
