Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7770 Vapor-X GHz OC Edition are massively better than the .

The has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The HD 7770 was released over three years more recently than the , and so the HD 7770 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the when running the latest games.

The HD 7770 has 1024 MB video memory, but the does not have an entry, so the two GPUs cannot be reliably compared in this area.

GPU Mini Review

Mini ReviewRadeon HD 7770 Vapor-X GHz OC Edition is a special edition of the fast-middle-class Radeon HD 7770. See the standard version for more information about it.
The differences include increased memory and core clocks, from 1125MHz to 1300MHz and from 1000MHz to 1100MHz, respectively. A new quiet and efficient cooling system, called Vapor-X, is also available.
Benchmarks indicate a 8% performance boost when compared to the standard Radeon HD 7770.
Benchmarks indicate that the most demanding games (e.g. Metro 2033) still require reduced settings to be played smoothly.
