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 9800 GT.

The GeForce 9800 GT has a 200 MHz higher core clock speed and 48 more Texture Mapping Units than the Pro Graphics. This results in the GeForce 9800 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 GeForce 9800 GT has a 200 MHz higher core clock speed and 12 more Render Output Units than the Pro Graphics. This results in the GeForce 9800 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 GeForce 9800 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 GeForce 9800 GT when running the latest games.

The GeForce 9800 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 9800 GT has 112. However, the actual shader performance of the Pro Graphics is 314 and the actual shader performance of the GeForce 9800 GT is 168. The Pro Graphics having 146 better shader performance is not particularly notable, as altogether the GeForce 9800 GT performs better when taking into account other relevant data.

The Pro Graphics transistor size technology is 43 nm (nanometers) smaller than the GeForce 9800 GT. This means that the Pro Graphics is expected to run much cooler and achieve higher clock frequencies than the GeForce 9800 GT.

The Iris Pro Graphics 5200 Desktop requires 28 Watts to run and the GeForce 9800 GT requires 105 Watts. We would recommend a PSU with at least 400 Watts for the GeForce 9800 GT, but we do not have a recommended PSU wattage for the Pro Graphics. The GeForce 9800 GT requires 77 Watts more than the Pro Graphics to run. The difference is significant enough that the GeForce 9800 GT may have an adverse affect on your yearly electricity bills in comparison to the Pro Graphics.

GPU Mini Review

Mini ReviewIris 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.
GeForce 9800 GT is a high-end GFX based on the 65nm variant of the first-shader unified architecture.
It's based on the G92 Core and offers 112 Shader Processing Units, 56 TMUs and 16 ROPs, on a 256-bit memory interface of GDDR3. The central unit runs at 600MHz and the memory clock operates 900MHz. It will consume no more than 105 Watt.
It's therefore a renamed GeForce 8800 GT and will offer exactly the same performance.
Today's modern demanding games can be played at medium (most) or high settings (some) smoothly. However, DirectX 11 based games aren't supported and its performance will decrease substantially, as the resolution increases.
