In terms of overall gaming performance, the graphical capabilities of the Intel HD i7 3770S are marginally better than the AMD Radeon HD 6450 Sapphire OC 512MB Edition.

The HD 6450 has a 100 MHz higher core clock speed and 4 more Texture Mapping Units than the HD i7 3770S. This results in the HD 6450 providing 3.4 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 HD 6450 has a 100 MHz higher core clock speed than the HD i7 3770S and the same number of Render Output Units. This results in the HD 6450 providing 0.4 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 HD i7 3770S was released over a year more recently than the HD 6450, and so the HD i7 3770S is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6450.

The HD 6450 has 512 MB video memory, but the HD i7 3770S does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD i7 3770S has 16 Shader Processing Units and the Radeon HD 6450 Sapphire OC 512MB Edition has 160. However, the actual shader performance of the HD i7 3770S is 74 and the actual shader performance of the HD 6450 is 60. The HD i7 3770S having 14 better shader performance is not particularly notable, as altogether the HD 6450 performs better when taking into account other relevant data.

The HD i7 3770S transistor size technology is 18 nm (nanometers) smaller than the HD 6450. This means that the HD i7 3770S is expected to run slightly cooler and achieve higher clock frequencies than the HD 6450. While they exhibit similar graphical performance, the HD i7 3770S should consume less power than the HD 6450.

The HD i7 3770S requires 77 Watts to run and the Radeon HD 6450 Sapphire OC 512MB Edition requires 18 Watts. We would recommend a PSU with at least 300 Watts for the HD i7 3770S and a PSU with at least 300 Watts for the HD 6450. The HD i7 3770S requires 59 Watts more than the HD 6450 to run. The difference is significant enough that the HD i7 3770S may have an adverse affect on your yearly electricity bills in comparison to the HD 6450.

GPU Mini Review

Mini ReviewOverview
Intel HD i7 3770S is the specific version of Intel HD Graphics 4000 Desktop that is Integrated in the Core i7-3770S Processor.

The Central Unit Initially Runs at 650MHz and goes up to 1150MHz, in Turbo Mode.

Frame Buffer: Up to 1.7GB.

Memory Channel: 64-bit Or 128-bit.

Memory Clock: Up to 800MHz.

Memory Bandwidth: It is then obvious the Memory Bandwidth depends on a lot of factors and thus this Graphics Card performance may vary heavily from system to system.

Gaming Benchmarks Indicate its Performance is Similar to of a Dedicated GeForce GT 620.

System Suggestions
We recommend 4GB of RAM for a system with Intel HD i7 3770S.
Radeon HD 6450 Sapphire OC 512MB Edition is a special edition of AMD's Entry-Level Radeon HD 6450, created by Sapphire.

Overclock: Central Unit
The Central Unit now runs at 750MHz, instead of 625MHz.

Overclock: Memory Clock
The Operating Memory Clock and the Frame Buffer both remain the same.

Cooling Solution
The Cooling System remains the same.

Benchmarks indicate a 11% performance over the reference Radeon HD 6450.
