NVIDIA Quadro P4200 vs Intel UHD Graphics P630 vs NVIDIA Quadro P5000 Max-Q

NVIDIA Quadro P4200

The Nvidia Quadro P4200 is a mobile high-end workstation graphics card for notebooks. It is based on the GP104 chip (like the consumer GeForce GTX 1070 or 1080 for laptops) and features 2304 shader cores. The clock rate is not disclosed but the theoretical SP performance is rated at 8.9 TFLOPs (for the fast Max-P version) and therefore faster than the old Quadro P5000 but below the Quadro P5200 (see table below). The P4200 is equipped with 8 GB GDDR5 which leads to 224 GB7s peak bandwidth due to the 256 Bit memory bus. There are two variants available, a Max-P performance version and a Max-Q version tuned for efficiency (with lower clock speeds).

The Quadro GPUs offer certified drivers, which are optimized for stability and performance in professional applications (CAD, DCC, medical, prospection, and visualizing applications). The performance in these areas is therefore much better compared to corresponding consumer GPUs.

Power Consumption

The power consumption of the Quadro P4200 is rated at 115 Watt TGP (max power consumption incl. memory) and therefore 15 Watt more than the Quadro P5000. The card is therefore best suited for large 17-inch notebooks.

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.

NVIDIA Quadro P5000 Max-Q

The Nvidia Quadro P5000 Max-Q (official Nvidia Quadro P5000 with Max-Q Design) is a mobile high-end workstation graphics card for notebooks. It is the power efficient variant of the normal Quadro P5000 for laptops and offers slightly reduced clock speeds (1101 - 1366 MHz versus 1164 - 1506 MHz) and a greatly reduced power consumption (80 versus 100 Watt TGP). Similar to the consumer GeForce GTX 1070 Max-Q (Laptop), it is based on a slimmed-down GP104 chip with 2048 shaders. The graphics card is designed for the Kaby Lake generation. 

The Quadro GPUs offer certified drivers, which are optimized for stability and performance in professional applications (CAD, DCC, medical, prospection, and visualizing applications). The performance in these areas is therefore much better compared to corresponding consumer GPUs.

Performance

The theoretical performance should be slightly below the normal Quadro P4000 due to the reduced clock speeds.

Power Consumption

With an TGP of 80 Watt, the P5000 Max-Q is only slightly higher rated (5 Watt) as the much slower Quadro P3000 (75 Watt) and therefore similar sized laptops can use the P5000 Max-Q.
