AMD Ryzen 9 4900HS vs Intel Core i9-9880H vs Intel Xeon E-2276M

AMD Ryzen 9 4900HS

The AMD Ryzen 9 4900HS is a mobile SoC for big laptops based on the Renoir architecture. The 4900HS integrates all eight cores based on the Zen 2 microarchitecture. They are clocked at 3 (guaranteed base clock) to 4.3 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured in the modern 7 nm process at TSMC and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips

According to our information, the Ryzen 9 4900HS is only slightly faster than the Ryzen 7 4800HS. The CPU is clocked 100 MHz (base and boost) higher, but the gains greatly depend on the cooling and TDP settings. Compared to Intel chips, the i9-9980HK top model should be comparable. That means the Ryzen 9 4900HS should be able to handle all demanding tasks and gaming. Compared to the similar named 45W-version, the Ryzen 9 4900H, the 4900HS is differs in 100 MHz boost and 300 MHz base clock.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics card with most likely 7 CUs. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB level 3 cache can be found on the chip. See our hub page on the Renoir Processors for more information.

The TDP of the APU is specified at 35 Watt (default). That means the chip is intended for big and relatively heavy laptops. The Ryzen 7 4900HS is the 35 Watt version of the R9 4900H with a 10 Watt lower TDP.

Intel Core i9-9880H

The Intel Core i9-9880H is a high-end processor for laptops with eight cores based on the Coffee Lake architecture (2019 refresh, CFL-HR). The processor clocks at between 2.3 - 4.8 GHz (4.1 GHz with 8 cores) and can execute up to sixteen 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 (not verified). Compared to the predecessor, the Core i9-8950HK, the 9980H is based on the same architecture but offers 2 more cores.

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 33% compared to a similar clocked predecessor and even up to 100% compared to older Kaby-Lake quad-cores. Single thread performance however only improved slightly and the multi-core performance is heavily depending on the cooling.

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.
