About 30% more performance is gained on average compared to a single GTX 470M (in high resolutions and with Anti-Aliasing).
Currently, the SLI driver support from Nvidia is better than the Crossfire support from AMD, leading to higher gains. Generally, the SLI gain depends on the used application/game and the driver support. The performance of the GTX 470M SLI combination should be similar to the GTX 480M SLI due to the high-clocked GTX470M cards. HD 5850).ĭetailed information on the GF104 architecture (and by extension also the GF106 and GF108) can be found in the desktop GTX 460 article by Anandtech.
Due to the different shader architectures and the higher clock rate of the shader domain, the core count can not be directly compared to AMD cores of the Radeon 5000 series (e.g. Because of these cutbacks, the size of the SM grew only by 25% despite the higher number of shaders and larger warp schedulers with superscalar dispatch capabilities.
The ECC memory protection, which is important for professional applications, was completely omitted and the FP64 hardware was shortened (only 1/3 of the shader are FP64-capable and therefore only 1/12 of the performance of the FP32). However, in worst case scenarios the performance can also be worse than that of the GF100 (and its predecessors). As there are still only 2 warp schedulers (versus 3 shader groups), Nvidia now uses superscalar execution to use the higher amount of shaders per SM more efficiently. In theory, the shaders can therefore be utilized more efficiently and the performance per core is improved. They feature more shaders (3x16 instead of 2x16), more texture units (8 instead of 4) and SFUs per streaming multi-processor (SM). In contrast to the GF100, which was designed for professional applications, these chips target the consumer market. Unlike the GF100, the smaller GF104, GF106, and GF108 cores were shortened and considerably modified. The architecture of the GF104 is not comparable to the old GT215 (e.g., GeForce GTS 350M) or G92b (e.g., GeForce GTX 285M) cores. The GTX 470M, however, offers only 288 cores of the 384 and a 192 Bit memory bus. The GF104 core of the GTX 470M is related to the GF100 core of the GeFore GTX 480M that offers 384 shaders and a 256 Bit memory bus for GDDR5.
The TDP can also be reduced to 4.9 Watts, but this will obviously affect the performance. The TDP of the whole Pentium Silver N5000 chip is 6 Watts by default, so the GPU is primarily used for (often passively cooled) netbooks or thin notebooks. Up to three displays can be connected via DP 1.2a/eDP 1.3 or HDMI 2.0a (including HDCP 2.2).
The video engine decodes H.265/HEVC (8b and 10b) and VP9 completely in hardware. Therefore, the GPU is only suited for some very low demanding games like Dirt Rally or Sims 4. The UHD Graphics 605 offers a similar performance as the Intel HD Graphics 505 in the Apollo Lake SoCs (same Gen 9 architecture). The technical specifications of the GPU are based on Intel's Gen9 architecture, which is also used for the more expensive Skylake series and also in the predecessor HD Graphics 505.ĭue to its lack of dedicated graphics memory or eDRAM cache, the UHD 605 has to access the main memory via processor (2x 64bit DDR4/LPDDR4-2400). Being the maximum configuration of the Gemini Lake GPU, the UHD Graphics 605 is equipped with 18 Execution Units (EUs) running at up to 750 MHz. The GPU can convince with low consumption figures, but the performance is only in the low-end segment and is rarely sufficient for modern games. Pentium Silver N5000), which was announced late 2017. The Intel UHD Graphics 605 is an integrated processor graphics unit from the Gemini Lake generation (e. Such a lack should not be taken to imply anything about the relative quality of such implementations of older OpenGL versions.Intel UHD Graphics 605 ► remove from comparison A lack of submission results for OpenGL 4.3 or earlier implementations means only that such implementations do not fall into the range for which Adopters are required to make conformance submissions to Khronos. Khronos introduced an Adopter program for OpenGL implementations starting with OpenGL 4.4, and Adopters are only required to submit conformance test results for implementations of OpenGL 4.4 and later versions.
