Intel UHD Graphics P630 vs AMD Radeon R9 M375 vs AMD Radeon R9 M390X
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.
AMD Radeon R9 M375

The AMD Radeon R9 M375 is a dedicated higher mid-range graphics card for laptops. It is still unclear if the M375 is based on a new chip (Tonga derivative with full DirectX 12 and Vulkan support) or the old Cape Verde chip from 2012. The core is clocked at relatively high 1015 MHz, however, the bottleneck may be the use of slow DDR3 graphics memory (128-bit).
Performance
If slow DDR3 graphics memory is used, the performance should be somewhere close to a Radeon R9 M270 (see for gaming benchmarks). Therefore, demanding games are running in low to medium details.
The 640 shaders can be used with OpenCL 1.2 for general-purpose calculations (as 10 compute units).
Features
Features of the R9-M375 include video decoding for MPEG-4 AVC/H.264, VC-1, MPEG-2, and Flash directly by the AMD GPU. Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD videos are compatible as well.
The R9 series also supports automatic graphics switching between the integrated GPU and discrete GPU. Called Enduro, the technology supersedes AMD's Dynamic Switchable Graphics and is similar to Nvidia's Optimus. Furthermore, the M375 can directly support multiple monitors using Eyefinity Technology if Enduro is disabled.
Other features include ZeroCore to reduce the power consumption when the display is turned off and Power Gating to power down areas of the chip that are not used.
The integrated HD audio processor is able to transmit HD Audio (TrueHD or DTS Master Audio) over HDMI and DisplayPort (e.g., for Blu-Ray videos). Additionally, it allows audio output simultaneously and in parallel to multiple devices with the new Discrete Digital Multipoint Audio (DDMA) feature.
AMD Radeon R9 M390X
► remove from comparison![AMD Radeon R9 M390X](typo3temp/_processed_/5/9/csm_radeon_m390x_3aeb687fd6.png)
The AMD Radeon R9 M390X is a mobile high-end graphics card for laptops. It is most likely based on the same chip as the AMD Radeon R9 M295X in the iMac 5K Late 2014. That means it should be based on the third generation of GCN (desktop Tonga chip). The amount of shader cores is identical but the core clock is reduced by 15% (from 850 MHz to 723 MHz) and the memory is also clocked slower (5448 MHz vs 5000 MHz).
The performance should be a bit below the M295X. Compared to the competition, the R9-M390X should be positioned somewhere between the GeForce GTX 965M and 970M and therefore suitable for high-end games in 1080p resolution and high detail settings.
The card was first mentioned by Alienware on their twitter account and should feature 4GB VRAM according to the tweet.
The power consumption should be rated around 100 Watt TDP and therefore suited only for large and bulky laptops (like the Alienware M17x it was announced in).
