In terms of overall gaming performance, the AMD Ryzen 5 4600H 6-Core 3.0GHz is massively better than the Intel Celeron M ULV 423 1.06GHz 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.

The Ryzen 5 4600H was released over three years more recently than the Celeron M ULV, and so the Ryzen 5 4600H is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Celeron M ULV when running the latest games.

The Ryzen 5 4600H has 5 more cores than the Celeron M ULV. With 6 cores, the Ryzen 5 4600H is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

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 5 4600H and Celeron M ULV 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 5 4600H has a 1.94 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 probably a good indicator that the Ryzen 5 4600H is superior.

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 5 4600H has a 3071 KB bigger L2 cache than the Celeron M ULV, and although the Celeron M ULV does not appear to have an L3 cache, its larger L2 cache means that it wins out 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.

The Ryzen 5 4600H has a 10 Watt lower Maximum TDP than the Celeron M ULV, and was created with a 58 nm smaller manufacturing technology. What this means is the Ryzen 5 4600H will consume slightly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill slightly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

The Ryzen 5 4600H has an on-board GPU, which means that it will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card. The Celeron M ULV, however, does not, and you will probably have to look for a dedicated card if you wish to use it at all.

On-board GPUs tend to be fairly awful in comparison to dedicated cards from the likes of AMD or Nvidia, but as they are built into the CPU, they also tend to be cheaper and require far less power to run (this makes them a good choice for laptops). We would recommend a dedicated card for running the latest games, but integrated GPUs are improving all the time and casual gamers may find less recent games perform perfectly acceptably.

CPU Mini Review

Mini ReviewThe AMD Ryzen 5 4600H 6-Core 3.0GHz is a high-end notebook APU based on AMD's 7nm Zen 2 microarchitecture. It offers 6 physical cores (12 logical), clocked at 3.0 GHz base clock speed and 4.0 GHz boost clock speed. It has a locked multiplier and therefore cannot be overclocked using traditional methods. It has 8MB 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 3MB L2 Cache and 384KB L1 Cache. This processor also supports DDR4 based RAMs with maximum memory support of 64GB. The AMD Ryzen 5 4600H 6-Core 3.0GHz has a maximum Thermal Power Design of 45W, making it a mid-range, power-efficient CPU that should extend laptop battery life. Among its many features are Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFX), Pure Power and Precision Boost are enabled. It features an integrated Vega 6 GPU with 6 Execution units, 384 Shaders, and a maximum clock speed of 1,500MHz. This is a mid-range graphics chip that can run less demanding eSports titles at 900p.Merom is the code name for various Intel processors that are sold as Core 2 Duo, Core 2 Solo, Pentium Dual-Core and Celeron. It was the first mobile processor to be based on the Core microarchitecture, replacing the Enhanced Pentium M based Yonah processor. Merom has product code 80537, which is shared with Merom-2M and Merom-L that are very similar but have a smaller L2 cache. Merom-L has only one processor core and a different CPUID model. The desktop version of Merom is Conroe and the dual-socket server version is Woodcrest. Merom has subsequently been replaced by Penryn.
