In terms of overall gaming performance, the graphical capabilities of the Intel HD i7 3770S are significantly better than the AMD Radeon HD 7450A.

The HD i7 3770S and the Radeon HD 7450A have the same core clock speed of 650 MHz, but the Radeon HD 7450A has 4 more Texture Mapping Units than the HD i7 3770S. As a result, the Radeon HD 7450A exhibits a 2.6 GTexel/s better Texture Fill Rate than the HD i7 3770S. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD i7 3770S and the Radeon HD 7450A have both the same core clock speed and the same Pixel Fill Rate. 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 less than a year after the Radeon HD 7450A, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 7450A has 1024 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 7450A has 160. However, the actual shader performance of the HD i7 3770S is 74 and the actual shader performance of the Radeon HD 7450A is 68. The HD i7 3770S having 6 better shader performance and an altogether better performance when taking into account other relevant data means that the HD i7 3770S delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon HD 7450A.

The HD i7 3770S transistor size technology is 18 nm (nanometers) smaller than the Radeon HD 7450A. This means that the HD i7 3770S is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 7450A.

The HD i7 3770S requires 77 Watts to run and the Radeon HD 7450A requires 25 Watts. We would recommend a PSU with at least 300 Watts for the HD i7 3770S. The HD i7 3770S requires 52 Watts more than the Radeon HD 7450A 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 Radeon HD 7450A.

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 7450A is used in All-In-One PCs. It's based on the Caicos chip and therefore features 160 Shader Processing Units on a 64-bit memory interface of standard DDR3. It's manufactured with either a 512MB or 1GB frame buffer and offers 8 TMUs and 4 ROPs.
Its gaming performance is below the average.
