In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7750 VTX3D 1GB DDR3 Edition are massively better than the Intel HD i5 661.

The HD 7750 was released over a year more recently than the HD i5 661, and so the HD 7750 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD i5 661.

The HD 7750 has 1024 MB video memory, but the HD i5 661 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD 7750 has 512 Shader Processing Units but the HD i5 661 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD i5 661 requires 87 Watts to run but there is no entry for the HD 7750. We would recommend a PSU with at least 400 Watts for the HD 7750.

GPU Mini Review

Mini ReviewRadeon HD 7750 VTX3D 1GB DDR3 Edition is a special edition of the fast-middle-class Radeon HD 7750 1GB DDR3.
This version has no new features (when compared to the DDR3 version) and so it performs exactly like it.
Intel HD i5 661 is a specific version of Intel GMA graphics that is built into the Intel Core i5 661 processor. This can handle most of the latest games like Call of Duty: Modern Warfare 3, Batman: Arkham City and The Elder Scrolls V: Skyrim on the lowest settings in a pretty good frame rate. Perfect fit for a non-hardcore gamer.
