AMD Ryzen 5 6600H vs Intel Core i9-8950HK vs Intel Xeon E-2276M

AMD Ryzen 5 6600H

The AMD Ryzen 5 6600H is a processor for big (gaming) laptops based of the Rembrandt generation. The R5 6600H integrates six of the eight cores based on the Zen 3+ microarchitecture. They are clocked at 3.3 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (12 threads). The chip is manufactured on the modern 6 nm TSMC process. 

The new Zen 3+ is a refresh of the Zen 3 architecture and should not offer a lot of changes. The chip itself however, offers a lot of new features, like support for USB 4 (40 Gbps), PCI-E Gen 4, DDR5-4800MT/s or LPDDR5-6400MT/s, WiFi 6E, Bluetooth LE 5.2, DisplayPort 2, and AV1 decode.

In the 6000 series, AMD finally switched to the current RDNA 2 graphics architecture for the iGPU. The 6600H only offers the slower Radeon 660M with 6 of the 12 CUs enabled and 1.9 GHz max. clock speed.

Performance

The average 6600H in our database is in the same league as the R7 5825U, the R7 6800U and also the Core i5-1340P, as far as multi-thread benchmark scores are concerned. This is a very decent result, as of late 2022.

Your mileage may vary depending on how high the CPU power limits are, and how competent the cooling solution of your system is.

Power consumption

This Ryzen 5 series APU has a default TDP, also known as the long-term power limit, of 45 W. A high-performance cooling solution is a must for a system built around such a chip.

The R5 6600H is built with TSMC's 6 nm process for great, as of early 2023, energy efficiency.

Intel Core i9-8950HK

The Intel Core i9-8950HK is a high-end processor for laptops with six cores based on the Coffee Lake architecture and was announced early 2018. The processor clocks at between 2.9- 4.8 GHz (4.3 GHz with 6 cores) and can execute up to twelve threads simultaneously thanks to Hyper-Threading. The 4.8 GHz can only be reached using the "Thermal Velocity Boost" which allows one core to boost to 4.8 GHz (+200 MHz) as long as the CPU temperature is below 50°C. Multiple cores can be boosted +100 MHz below 50°C.

According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. The i9-8950HK is the fastest model of the Coffee-Lake-H series at the time of announcement and offers an unlocked multiplier for overclocking of the CPU.

The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).

Performance

Due to the two additional cores, performance has increased by almost 50% compared to a similar clocked Kaby Lake processor.

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz. The architecture is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP with 45 watts and therefore the i9 is only suited for big laptops with good cooling solutions.

Intel Xeon E-2276M

The Intel Xeon E-2276M is a high-end processor for professional laptops with six cores based on the Coffee Lake architecture. The processor clocks at between 2.8 - 4.7 GHz and can execute up to twelve threads simultaneously thanks to Hyper-Threading / SMT. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. Compared to the similar consumer Core i7-9850H, the mobile Xeon offers support for ECC main memory and clocks 100-200 MHz higher.

The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).

Performance

The Xeon E-2276M is a high end processor in 2019 and therefore well suited for all tasks. Thanks to the high Turbo Boost, the single core performance is also very good. Long term performance however is very depending on good cooling and proper TDP settings and differs therefore for each laptop.

Graphics

The integrated Intel UHD Graphics P630 iGPU is the same as the old Intel HD Graphics P630 and the only difference to the UHD Graphics 630 in the consumer models are the professional drivers.

Power Consumption

Intel specifies the TDP with 45 watts and therefore the Xeon is only suited for big laptops with good cooling solutions.
