In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3850 AGP are noticeably better than the Intel HD i7 4790K.

The HD 3850 has a 318 MHz higher core clock speed and 12 more Texture Mapping Units than the HD i7 4790K. This results in the HD 3850 providing 9.3 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 3850 has a 318 MHz higher core clock speed and 14 more Render Output Units than the HD i7 4790K. This results in the HD 3850 providing 10 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 4790K was released over three years more recently than the HD 3850, and so the HD i7 4790K is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 3850 when running the latest games.

The HD 3850 has 512 MB video memory, but the HD i7 4790K does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD i7 4790K has 20 Shader Processing Units and the Radeon HD 3850 AGP has 320. However, the actual shader performance of the HD i7 4790K is 100 and the actual shader performance of the HD 3850 is 214. The HD 3850 having 114 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 3850 delivers a noticeably smoother and more efficient experience when processing graphical data than the HD i7 4790K.

The HD i7 4790K transistor size technology is 33 nm (nanometers) smaller than the HD 3850. This means that the HD i7 4790K is expected to run much cooler and achieve higher clock frequencies than the HD 3850.

The HD i7 4790K requires 88 Watts to run and the Radeon HD 3850 AGP requires 75 Watts. We would recommend a PSU with at least 300 Watts for the HD i7 4790K and a PSU with at least 450 Watts for the HD 3850. The HD i7 4790K requires 13 Watts more than the HD 3850 to run. The difference is not significant enough for the HD i7 4790K to have a noticeably larger impact on your yearly electricity bills than the HD 3850.

GPU Mini Review

Mini ReviewOverview
Intel HD i7 4790K is the specific version of Intel HD Graphics 4600 Desktop that is Integrated in the Core i7-4790K Processor.

GPU
The Central Unit Initially Runs at 350MHz and goes up to 1250MHz, in Turbo Mode.

Memory
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.

Performance
Gaming Benchmarks Indicate its Performance is Similar to of a Dedicated GeForce GT 220.

System Suggestions
We recommend 4GB of RAM for a system with Intel HD i7 4790K.
Radeon HD 3850 AGP is a variant of the high-end Radeon HD 3850 based on the 55nm, second unified shader architecture, R600. Check its page to know more about its Core.
Compared to Radeon HD 3850, it features twice as much video memory and an AGP 8X Bus Interface. Benchmarks indicate the double sized frame buffer benefits this GPU largely and so its performance is up to 8% better than the reference Radeon HD 3850.
Today's modern games should run fluently at medium settings but with modest resolutions. DirectX 11 games aren't supported.
