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 Ryzen 9 5980HX is a top-end laptop CPU based on AMD's 7nm+ Zen 3 microarchitecture. It offers 8 physical cores (16 logical), initially clocked at 3.3GHz, which may go up to 4.8GHz using Precision Boost. It has an unlocked multiplier, therefore, it can be overclocked using traditional methods. As an AMD 'X' CPU, the Ryzen 9 5980HX can use eXtended Frequency Range (XFR) for automated overclocking. 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 45W. This makes the Ryzen 9 5980HX a mobile CPU, although this is in-line with the high core count. 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.

Gaming Performance Comparison

In terms of overall gaming performance, the AMD Ryzen 9 5980HX 8-Core 3.3GHz is massively better than the AMD Ryzen 7 5800HS 8-Core 2.8GHz 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 Ryzen 9 5980HX 8-Core 3.3GHz 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 Ryzen 9 5980HX 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 AMD Ryzen 9 5980HX 8-Core 3.3GHz have the same number of threads. Both the Ryzen 7 5800HS and the Ryzen 9 5980HX use hyperthreading. The Ryzen 7 5800HS has 2 logical threads per physical core and the Ryzen 9 5980HX 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 the Ryzen 9 5980HX are from the same family of CPUs, and thus their clock speeds are directly comparable. With this in mind, it is safe to say that with a 0.5 GHz faster base clock rate, the Ryzen 9 5980HX manages to provide noticeably better performance than the <span class='gpu1Mention'>Ryzen 7 5800HS</span>.

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 Ryzen 7 5800HS and the Ryzen 9 5980HX have the same L2 cache size, and the same L3 cache size, so in terms of cache-related gaming performance, we have to look back to the clock rate, where the Ryzen 9 5980HX wins out.

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.
