AMD Radeon 760M vs Intel HD Graphics 5000 vs Intel HD Graphics 405 (Braswell)

AMD Radeon 760M

The AMD Radeon 760M is an integrated GPU in the Ryzen 7040 series for laptops (Phoenix, e.g. Ryzen 5 7640HS). The iGPU is based on the new RDNA3 architecture and has 8 of the 12 CUs (= 512 shaders) clocked at up to 2.8 GHz (depending on the CPU model). As the predecessor Radeon 660M, the 760M supports hardware raytracing, although the performance is too slow to use it in current games.

Thanks to the new architecture and higher clock speeds, the Radeon 760M should be clearly faster then the old Radeon 660M.

Thanks to the modern 4nm process and clever power-saving features, the power consumption is comparatively low (according to AMD). The whole chip of the first two models can be configured between 15 - 54 Watt TDP.

Intel HD Graphics 5000

The Intel HD Graphics 5000 (GT3) is a processor graphics card included in some of the ULV Haswell processors of 2013 (e.g. Core i5-4250U). It represents the highest configuration of the integrated graphics unit (40 execution units), but lacks the additional eDRAM cache of the Iris Pro Graphics 5200. The relatively low base clock can be automatically overclocked using Turbo Boost technology. Depending on the processor model, the base and turbo clock rates may differ, resulting in varying graphics performance between CPU models.

In comparison to the HD 4000, the graphics core has been modified extensively. The GPU supports DirectX 11.1, OpenCL 1.2 and OpenGL 4.0. It also features an improved decoder for 4K videos and the fast Quick Sync encoder.

According to benchmarks in 3DMark 11, the HD Graphics 5000 is up to 50 percent faster than the previous HD 4000. In games, however, the performance advantage is significantly lower. With simultaneous load on the CPU, the low TDP of the ULV models (15 W) limits the Turbo Boost of the GPU. Although the HD 5000 features 40 Execution Units, the graphics performance is still somewhat below the HD Graphics 4600 with only 20 EUs (HD 4000: 16 EUs). Overall, the HD 5000 is thus just behind the AMD Radeon HD 7660G and at the level of a dedicated Radeon HD 7650M. Current games (as of 2013) will run fluently in low to medium-low settings.

Due to the 22nm 3D Tri-Gate production process, power consumption is relatively low. The HD Graphics 5000 is available on certain ULV dual-core Haswell models in the 15 Watt TDP range.

Intel HD Graphics 405 (Braswell)

The Intel HD Graphics 405 (Braswell)  is an integrated graphics card in the low end SoCs of the Braswell series (e.g. Pentium N3710). It is based on the same architecture as the integrated GPU of the Broadwell graphics cards (e.g. HD Graphics 5300), but offers less shader cores and slower clock speeds.

The GPU was simply called Intel HD Graphics (Broadwell) before 2016 and included also the slower 12 EUs version in the Celeron model. The Graphics 405 name currently only stands for 16-core-versions in Pentium models. The 12 EU version is now called Intel HD Graphics 400.

The clock speed and memory configuration can still vary from model to model.

Gaming performance ist still only suited for older or less demanding games. Often also the processor is limited gaming performance (e.g. in the dual-core N3000).

The SoC also integrates a video decoding engine that should be able to handle 4K H.265 videos.
