Intel Iris Pro Graphics 6200 vs Intel UHD Graphics P630

Intel Iris Pro Graphics 6200

The Intel Iris Pro Graphics 6200 (GT3e) is an integrated graphics card and the fastest GPU of the Broadwell generation. It is built into several high-end CPUs specified at 47 W TDP. The so-called GT3e GPU offers a fast eDRAM cache as well as 48 EUs (Execution Units) and therefore somewhat more shader power than the previous Iris Pro Graphics 5200. The clock range depends on the model it is built into (up to 1150 MHz with Turbo Boost).

Architecture and Features

Broadwell features a GPU based on the Intel Gen8 architecture, which has been optimized in various aspects compared to the previous Gen7.5 (Haswell). Inter alia, the shader arrays called "subslice" have been reorganized and now offer 8 Execution Units (EUs) each. Three subslices form a "slice" for a total of 24 EUs. Combined with other improvements such as larger L1 caches and an optimized frontend, the integrated GPU has become faster and more efficient than its predecessor.

The Iris Pro Graphics 6200 represents the high-end "GT3e" version of the Broadwell GPU family and consists of two slices with 48 EUs in total. In addition, there is also a fast eDRAM cache (128 MB), which can be found only on the Iris Pro.

All Broadwell GPUs support OpenCL 2.0 and DirectX 12 (FL 11_1). The video engine can now decode H.265 using both fixed function hardware as well as available GPU shaders. Up to three displays can be connected via DP 1.2/eDP 1.3 (max. 3840 x 2160 @ 60 Hz) or HDMI 1.4a (max. 3840 x 2160 @ 24 Hz). HDMI 2.0, however, is not supported.

Performance

Depending on the benchmark, the Iris Pro Graphics 6200 performs similar to a dedicated GeForce GT 750M or GeForce 940M. Many games of 2014/2015 can be played fluently in WXGA resolution (1366 x 768) and medium detail settings. However, very demanding games such as The Witcher 3 will require lower resolutions and/or details.

Power Consumption

Utilizing a new 14 nm FinFET process, the Iris Pro Graphics 6200 is specified at 47 W TDP (entire chip including CPU, GPU and memory controller) and therefore suited for medium-sized notebooks. The TDP is flexible and can be further reduced (37 W), which has a significant impact on performance.

Intel UHD Graphics P630

The Intel UHD Graphics P630 (GT2) is a professional integrated graphics card, which can be found in various Xeon desktop and notebook processors of the Coffee-Lake generation. The "GT2" version of the GPU offers 24 Execution Units (EUs) and the clocks depend on the CPU model. Due to its lack of dedicated graphics memory or eDRAM cache, the UHD P630 has to access the main memory (2x 64-bit DDR3L-1600 / DDR4-2133). Compared to the older HD Graphics P630 (Kaby-Lake), the newer UHD GPU is identical but can be clocked slightly higher. Compared to the regular UHD 630, the P630 supports ECC main memory and is intended for professional applications.

Performance

The exact performance of the UHD Graphics P630 depends on various factors like TDP, L3 Cache, memory (DDR3/DDR4) and maximum clock rate of the specific model. However, it should be fairly similar to the HD Graphics 530 and HD Graphics 630 and therefore only suited for low demanding games like Overwatch or Farming Simulator 2017 (low details).

Features

The features of the UHD P630 are the same as for the HD 630 and therefore H.265/HEVC Main10 profile at 10-bit color depth are supported in hardware. Furthermore, HDCP 2.2 is also supported in all chips, which allows Netflix 4K videos, for instance. HDMI 2.0 however is still only supported with an external converter chip (LSPCon).

Power Consumption

The UHD Graphics P630 can be found in several notebook and desktop processors of different TDP classes.
