CPU Mini Review

Mini Review The Ryzen 7 5800HS is a mid to top-end gaming laptop CPU based on AMD's 7nm+ Zen 3 microarchitecture. It offers 8 physical cores (16 logical), initially clocked at 2.8GHz, which may go up to 4.4GHz using Precision Boost. It has 20MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. This processor also supports DDR4 based RAMs with maximum memory support of 64GB. It has a maximum Thermal Power Design of 35W. This makes the Ryzen 7 5800HS a portable mobile CPU. Among its many features are Simultaneous Multithreading, Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFR), Pure Power and Precision Boost are enabled. It features an integrated AMD Radeon Vega GPU with 11 Compute Units that offers low-end graphical performance. The Intel Core i9-9880H 8-Core 2.3GHz is a high-end CPU based on Intel's 14nm Coffee Lake refresh microarchitecture. It offers 8 physical cores (16 logical), initially clocked at 2.3GHz, which may go up to 4.7GHz using Turbo Boost. It does not feature an unlocked multiplier and therefore cannot be overclocked using traditional methods. It has 16MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. It also has 2MB L2 cache and 512KB L1 cache. This processor also supports DDR4 based RAMs with maximum memory support of 128GB. It has a maximum Thermal Power Design of 45W (including the onboard GPU). It is a fairly power efficient processor. Among its many features, HyperThreading, Turbo Boost 2.0 and Virtualization are activated are enabled. It features Intel UHD Graphics 630 integrated GPU with 350MHz base clock and turbo boost frequency of 1.2GHz. Video memory will depend on the amount of RAM paired with CPU but the maximum limit is 64GB.

Gaming Performance Comparison

In terms of overall gaming performance, the AMD Ryzen 7 5800HS 8-Core 2.8GHz is massively better than the Intel Core i9-9880H 8-Core 2.3GHz when it comes to running the latest games. This also means it will be less likely to bottleneck more powerful GPUs, allowing them to achieve more of their gaming performance potential.

Both the Ryzen 7 5800HS 8-Core 2.8GHz and the Core i9-9880H 8-Core 2.3GHz were released at the same time, so are likely to be quite similar.

Both CPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings (assuming they are accompanied by equivalently powerful GPUs).

{ The Ryzen 7 5800HS and the Core i9-9880H 8-Core both have 8 cores. Games are not yet able to harness this many cores, so it is probably excessive if you mean to just run the latest games; however, if you intend on running a server with this CPU, it would seem to be a decent choice.

Both the AMD Ryzen 7 5800HS 8-Core 2.8GHz and the Intel Core i9-9880H 8-Core 2.3GHz have the same number of threads. Both the Ryzen 7 5800HS and the Core i9-9880H 8-Core use hyperthreading. The Ryzen 7 5800HS has 2 logical threads per physical core and the Core i9-9880H 8-Core has 2.

Multiple threads are useful for improving the performance of multi-threaded applications. Additional cores and their accompanying thread will always be beneficial for multi-threaded applications. Hyperthreading will be beneficial for applications optimized for it, but it may slow others down. For games, the number of threads is largely irrelevant, as long as you have at least 2 cores (preferably 4), and hyperthreading can sometimes even hit performance.

More important for gaming than the number of cores and threads is the clock rate. Problematically, unless the two CPUs are from the same family, this can only serve as a general guide and nothing like an exact comparison, because the clock cycles per instruction (CPI) will vary so much.

The Ryzen 7 5800HS and Core i9-9880H 8-Core are not from the same family of CPUs, so their clock speeds are by no means directly comparable. Bear in mind, then, that while the Ryzen 7 5800HS has a 0.5 GHz faster frequency, this is not always an indicator that it will be superior in performance, despite frequency being crucial when trying to avoid GPU bottlenecking. In this case, however, the difference is enough that it possibly indicates the superiority of the .

Aside from the clock rate, the next-most important CPU features for PC game performance are L2 and L3 cache size. Faster than RAM, the more cache available, the more data that can be stored for lightning-fast retrieval. L1 Cache is not usually an issue anymore for gaming, with most high-end CPUs eking out about the same L1 performance, and L2 is more important than L3 - but L3 is still important if you want to reach the highest levels of performance. Bear in mind that although it is better to have a larger cache, the larger it is, the higher the latency, so a balance has to be struck.

The <span class='gpu1Mention'>Ryzen 7 5800HS</span> has a 4096 KB bigger L2 cache than the <span class='gpu2Mention'>Core i9-9880H 8-Core</span>, but on the other hand, it is the <span class='gpu2Mention'>Core i9-9880H 8-Core</span> that has a 16364 MB bigger L3 cache than the <span class='gpu1Mention'>Ryzen 7 5800HS</span>. In this case, the L2 size is probably what counts, so the <span class='gpu1Mention'>Ryzen 7 5800HS</span> is likely superior in this area.

The maximum Thermal Design Power is the power in Watts that the CPU will consume in the worst case scenario. The lithography is the semiconductor manufacturing technology being used to create the CPU - the smaller this is, the more transistors that can be fit into the CPU, and the closer the connections. For both the lithography and the TDP, it is the lower the better, because a lower number means a lower amount of power is necessary to run the CPU, and consequently a lower amount of heat is produced.
