In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270X Sapphire Toxic 2GB OC Edition are massively better than the Intel Iris i5 5675C.

The R9 270X has a 800 MHz higher core clock speed and 72 more Texture Mapping Units than the Iris i5 5675C. This results in the R9 270X providing 85.6 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 R9 270X has a 800 MHz higher core clock speed and 30 more Render Output Units than the Iris i5 5675C. This results in the R9 270X providing 34.6 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 Iris i5 5675C was released over a year more recently than the R9 270X, and so the Iris i5 5675C is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the R9 270X.

The R9 270X has 1920 MB more video memory than the Iris i5 5675C, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 270X also has superior memory performance overall.

The R9 270X has 179.2 GB/sec greater memory bandwidth than the Iris i5 5675C, which means that the memory performance of the R9 270X is massively better than the Iris i5 5675C.

The Iris i5 5675C has 48 Shader Processing Units and the Radeon R9 270X Sapphire Toxic 2GB OC Edition has 1280. However, the actual shader performance of the Iris i5 5675C is 53 and the actual shader performance of the R9 270X is 1251. The R9 270X having 1198 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 270X delivers a massively smoother and more efficient experience when processing graphical data than the Iris i5 5675C.

The Iris i5 5675C transistor size technology is 14 nm (nanometers) smaller than the R9 270X. This means that the Iris i5 5675C is expected to run slightly cooler and achieve higher clock frequencies than the R9 270X.

The Iris i5 5675C requires 65 Watts to run and the Radeon R9 270X Sapphire Toxic 2GB OC Edition requires 180 Watts. We would recommend a PSU with at least 300 Watts for the Iris i5 5675C and a PSU with at least 500 Watts for the R9 270X. The R9 270X requires 115 Watts more than the Iris i5 5675C to run. The difference is significant enough that the R9 270X may have an adverse affect on your yearly electricity bills in comparison to the Iris i5 5675C.

GPU Mini Review

Mini ReviewOverview
Intel Iris i5 5675C is the Specific Version of Intel Iris Pro Graphics 6200 Desktop that is Integrated in the Core i5-5675C Processor.

The Central Unit Initially Runs at 300MHz and goes up to 1100MHz, in Turbo Mode.

Unlike the common Integrated Graphics Cards, this one has access to a dedicated frame buffer of 128MB of eDRAM.
The GPU also Shares the System's RAM which varies from laptop to laptop. Typically, the GPU reserves 1GB. Depending on whether or not the system's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit memory interface. The operating memory clock also depends on the at which speed the System's RAM is running and is limited by the highest operating speed that the Processor supports. In this case, it is 800MHz.
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.

System Suggestions
We recommend 4GB of RAM for a system with Intel Iris HD i5 5675C.
Radeon R9 270X Sapphire Toxic 2GB OC Edition is a special edition of the high-end Radeon R9 270X.
This edition comes with a custom cooling system called "Tri-X", which reduces the card's temperature under load, significantly and comes overclocked out of the box in the central unit that was increased from 1000MHz to 1100MHz, while the Boost clock is now of 1150MHz. Also, the operating memory clock is now of 1500MHz.
Benchmarks indicate a 5% performance boost over the standard edition and so this card will surpass a Radeon HD 7950.
