AMD A10-8700P vs Intel Core i5-7600K vs Intel Core i5-7267U

AMD A10-8700P

The AMD A10-8700P is a mid-range Carrizo APU of 2015 for mainstream laptops. It is a SoC containing two Excavator CPU modules (with 4 integer and 2 FP units counted as 4 compute cores), a Radeon R7 graphics card with 6 compute cores (384 shaders), a DDR3-2133 (35 Watt cTDP) memory controller and a video engine (including UVD 6 with hardware HEVC / H.265 decoding).

The performances of the CPU and GPU cores depend on the configurable TDP. This cTDP can range from 12 to 35 Watts depending on the cooling solution and size of the laptop. Thus, clock speeds of the compute cores will vary. E.g., the GPU can score between 1764 points (15 Watts) to 2359 points (+34% with 35 Watt cTDP) in 3DMark 11 (P). CPU performance with a 35 Watt cTDP should be slightly above the Kaveri A10-7400P. If configured at 15 Watts, the CPU should be clearly slower as the Boost speed cannot be maintained for extended periods.

Intel Core i5-7600K

The Intel Core i5-7600K is a fast quad-core processor for desktops based on the Kaby Lake architecture and was announced in January 2017. It is the top model of the consumer Kaby-Lake-H Core i5 series at the time of the announcement. The i5 does not support HyperThreading (4 threads only) and runs from 3.8 (base speed) up to 4.2 GHz. As a K-model, the i5-7600K offers an open multiplicator for overclocking.

Architecture

Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.

Performance

The performance of the i5-7600K is about 10 percent above the predecessor Core i5-6600K, thanks to clock speed increases and long hold Turbo Boost clocks. Matching clock speed, there is no speed improvement from Skylake. The old top model Core i7-4790K however is still slightly faster.

More information with gaming benchmarks and power measurements can be found in our AMD Ryzen 7 versus Intel CPUs review (upcoming).

Graphics

The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 1150 MHz. The performance depends a lot on the memory configuration; it should be comparable to a dedicated Nvidia GeForce 920M in combination with fast DDR4-2133 dual-channel memory.

Contrary to Skylake, Kaby Lake now supports hardware decoding for H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors, which were announced in January, should also support HDCP 2.2.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency slightly. Intel still specifies the TDP with 91 Watts, which is a lot more than the 45 Watts of the mobile Kaby-Lake-H CPUs.

Intel Core i5-7267U

The Intel Core i5-7267U is a fast dual-core SoC for notebooks based on the Kaby Lake architecture and was announced in January 2017. The CPU has two processor cores clocked at 3.1-3.5 GHz (two cores also up to 3.5 GHz). The processor can execute up to four threads simultaneously thanks to Hyper Threading. It is also equipped with an Intel Iris Plus Graphics 650 GPU with 64 MB eDRAM, a dual-channel memory controller (DDR4) as well as VP9 and H.265 video decoding as well as encoding. The chip is still manufactured in a 14nm process with FinFET transistors.

Architecture

Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.

Performance

The performance of the 28-Watt CPU should be on par with the Core i7-7500U (2.7-3.5 GHz, no eDRAM, 15 Watts), but it should be a bit slower on practice due to the missing level 4 eDRAM and the lower TDP. This means the i5 is still one of the faster dual-core processors and should be sufficient for most scenarios. Some games might still require a real quad-core processor and therefore nit run perfectly on the dual-core processor, despite Hyper Threading.

Graphics

The integrated Intel Iris Plus 650 Graphics is the GT3e model of the Kaby Lake GPU (Intel Gen. 9.5). It has 48 Execution Units running at 300-1050 MHz and the performance is comparable to a GeForce 920MX thanks to fast eDRAM cache. However, there aren't any significant improvements compared to the old Iris Pro 550, so modern games can often not be played smoothly or only at the lowest or medium settings, respectively.

Contrary to Skylake, Kaby lake now also supports H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors announced in January should also support HDCP 2.2.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency even further. Intel specifies the TDP with 28 Watts, which can be reduced to 23 Watts (cTDP Down) depending on the usage scenario. The TDP is pretty high compared to the common 15-Watt TDP for dual-core processors, but allows a better utilization of CPU and GPU Turbo.
