CPU Mini Review

Mini Review The Intel Core i7-8809G 4-Core 3.1GHz is a high-end CPU based on Intel's 14nm Kaby Lake G microarchitecture. It offers 4 physical cores (8 logical), initially clocked at 3.1GHz, which may go up to 4.2GHz using Turbo Boost. It doesn't feature an unlocked multiplier therefore it can't 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. This processor also supports DDR4 based RAMs with maximum memory support of 64GB. It has a maximum Thermal Power Design of 100W (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 HD Graphics 630 integrated GPU with 350MHz base clock and turbo boost frequency of 1.15GHz. Video memory will depend on the amount of RAM paired with CPU but maximum limit is 64GB. In addition, the Core i7-8809G 4-Core 3.1GHz features a Radeon RX Vega M GH dedicated Graphics processor. It equips a GPU Codenamed Vega M which offers 24 Compute Units, 96 TMUs and 64 ROPs. The Central Unit Initially Runs at 1063MHz and goes up to 1190MHz in Turbo Mode. The GPU utilises its own onboard HBM2 memory. Radeon RX Vega M GH has 4GB of second-generation High Bandwidth Memory, clocked at 1.6Gb/s. Sat on a 1024-bit memory interface, this provides total memory bandwidth of 2.4GB/s. The Most Powerful Variant Offers Performance similar to a dedicated GeForce GTX 1060. This Intel Core i7-8809G CPU is likely to offer excellent computational performance and will not be the bottleneck in any modern gaming PC. Core i7-4810MQ 4-Core 2.8GHz is a high-end mobile processor based on the 22nm, Haswell microarchitecture. <br/> <br/> It offers 4 Physical Cores (8 Logical), initially clocked at 2.8GHz, which may go up to 3.8GHz and 6MB of L3 Cache. <br/> Among its many features, <b>HyperThreading, Turbo Boost and Virtualization</b> are activated. <br/> <br/> The processor integrates powerful Graphics called <b>Intel HD Graphics 4600</b>, with 20 Execution Units, initially clocked at 400MHz and that go up to 1300MHz, in Turbo Mode which share the L2 Cache and system RAM with the processor. <br/> Both the processor and integrated graphics have a rated board TDP of 57W. <br/> <br/> Its performance is exceptional. Therefore, it can be paired with even the most powerful dedicated graphics.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Core i7-8809G 4-Core 3.1GHz is noticeably better than the Intel Core i7-4810MQ 4-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 Core i7-8809G 4-Core 3.1GHz and the Core i7-4810MQ 4-Core 2.8GHz 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 Core i7-8809G 4-Core and the Core i7-4810MQ 4-Core both have 4 cores, which is not likely to be a limiting factor for gaming.

Both the Intel Core i7-8809G 4-Core 3.1GHz and the Intel Core i7-4810MQ 4-Core 2.8GHz have the same number of threads. Both the Core i7-8809G 4-Core and the Core i7-4810MQ 4-Core use hyperthreading. The Core i7-8809G 4-Core has 2 logical threads per physical core and the Core i7-4810MQ 4-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 Core i7-8809G 4-Core and Core i7-4810MQ 4-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 Core i7-8809G 4-Core has a 0.3 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 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.
