Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Intel Iris Pro Graphics 5200 Desktop are noticeably better than the Nvidia GeForce 8800 GT 1GB.
The 8800 GT has a 200 MHz higher core clock speed and 48 more Texture Mapping Units than the Pro Graphics. This results in the 8800 GT providing 30.4 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 8800 GT has a 200 MHz higher core clock speed and 12 more Render Output Units than the Pro Graphics. This results in the 8800 GT providing 8 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 Pro Graphics was released over three years more recently than the 8800 GT, and so the Pro Graphics is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 8800 GT when running the latest games.
The 8800 GT has 1024 MB video memory, but the Pro Graphics does not have an entry, so the two GPUs cannot be reliably compared in this area.
The Iris Pro Graphics 5200 Desktop has 160 Shader Processing Units and the GeForce 8800 GT 1GB has 112. However, the actual shader performance of the Pro Graphics is 314 and the actual shader performance of the 8800 GT is 168. The Pro Graphics having 146 better shader performance is not particularly notable, as altogether the 8800 GT performs better when taking into account other relevant data.
The Pro Graphics transistor size technology is 43 nm (nanometers) smaller than the 8800 GT. This means that the Pro Graphics is expected to run much cooler and achieve higher clock frequencies than the 8800 GT.
The Iris Pro Graphics 5200 Desktop requires 28 Watts to run and the GeForce 8800 GT 1GB requires 105 Watts. We would recommend a PSU with at least 450 Watts for the 8800 GT, but we do not have a recommended PSU wattage for the Pro Graphics. The 8800 GT requires 77 Watts more than the Pro Graphics to run. The difference is significant enough that the 8800 GT may have an adverse affect on your yearly electricity bills in comparison to the Pro Graphics.

| Mini Review | Iris Pro Graphics 5200 Desktop are found in some of the 2013 Haswell desktop processors.
They feature 40 Execution Units (160 Shader Processing Units), 8 TMUs and 4 ROPs. They share system memory and so the memory channel and speed will depend on the users configuration. The best possible combination is a dual-channel bus-width with an operating memory clock of 800MHz.
Its central unit and turbo frequency also depend on the CPU its embedded but it ranges from 400MHz to 1300MHz.
Compared to Iris Graphics 5100 Desktop, they offer an additional eDRAM cache of 128MB and so might offer performance identical to a dedicated GeForce GT 640 or a Radeon HD 6670. | | | | This is the 1GB variant of the high-end GeForce 8800 GT. Check the page of the standard edition to know more about its Core.
This edition features a 1GB frame buffer instead of 512MB. As a result, it performs significantly better at higher resolutions but offers identical performance at lower resolutions.
Overall, it's better than GeForce 8800 GT but still worse than GeForce 8800 GTS 512MB, despite featuring twice as much video memory. |
