NVIDIA GeForce GTX 660 Ti vs Intel UHD Graphics 630 vs Intel HD Graphics 630

NVIDIA GeForce GTX 660 Ti

The NVIDIA GeForce GTX 660 Ti is a high-end desktop graphics card based on the GK104 Kepler chip. It supports DirectX 11 and is manufactured in 28nm at TSMC. The core clock can be up to 980 MHz under load (GeForce Boost) and is a tleast 915 MHz. The GDDR5 VRAM is usually clocked at 1500 MHz (6000 MHz effective data rate).

Due to the higher core clock speed, the performance of the desktop GTX 660Ti is above the mobile GTX 680M (altough the 680M offers a wider memory bus of 256 Bit). Demanding games of 2013 should run in 1920x1080 with maximum settings and 4x Antialiasing fluently. Only Company of Heroes 2 and Hitman: Absolution scored below 30fps in our benchmarks on the average.

The chip offers the 5th generation video processor VP5, which is able to decode MPEG-1, 2, 4, H.264, VC1/WMV9 with a resolution of up to 4K. Furthermore, the included vidoe encoder called NVENC is able to encode H.264 vidoes without stressing the CPU.

The Geforce GTX 660Ti is rated at 150 Watt TDP and the default design uses two 6-pin power connectors.

Beware: For our benchmarks we used a slightly overclocked version that ran with 980-1059 MHz compared to the default 915 - 980 MHz. 

Intel UHD Graphics 630

The Intel UHD Graphics 630 (GT2) is an integrated graphics card, which can be found in various 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 630 has to access the main memory (2x 64-bit DDR3L-1600 / DDR4-2133). Compared to the older HD Graphics 630 (Kaby-Lake), the newer UHD GPU is identical but can be clocked slightly higher.

Performance

The exact performance of the UHD Graphics 630 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 630 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 630 can be found in several notebook and desktop processors of different TDP classes (35 - 91 W).

Intel HD Graphics 630

The Intel HD Graphics 630 (GT2) is an integrated graphics card, which can be found in various desktop and notebook processors of the Kaby-Lake generation (Kaby-Lake-H quad-core chip). 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 HD 630 has to access the main memory (2x 64-bit DDR3L-1600 / DDR4-2133).

Performance

The exact performance of the HD Graphics 630 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 (see for gaming benchmarks) and therefore only suited for low demanding games like Overwatch or Farming Simulator 2017 (low details).

Features

The revised video engine in the Kaby Lake chips now supports H.265/HEVC Main10 profile at 10-bit color depth and also the VP9 codec 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 HD Graphics 630 can be found in several notebook and desktop processors of different TDP classes (35 - 91 W). Thanks to the improved 14nm+ process, the power consumption could be slightly lower compared to Skylake CPUs.
