In terms of overall gaming performance, the Intel Core i7-4810MQ 4-Core 2.8GHz is massively better than the Intel Core i7-820QM 4-Core 1.73GHz 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 Core i7-4810MQ 4-Core was released over three years more recently than the Core i7-820QM 4-Core, and so the Core i7-4810MQ 4-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Core i7-820QM 4-Core when running the latest games.

The Core i7-4810MQ 4-Core and the Core i7-820QM 4-Core both have 4 cores, which is not likely to be a limiting factor for gaming.

Both the Intel Core i7-4810MQ 4-Core 2.8GHz and the Intel Core i7-820QM 4-Core 1.73GHz have the same number of threads. Both the Core i7-4810MQ 4-Core and the Core i7-820QM 4-Core use hyperthreading. The Core i7-4810MQ 4-Core has 2 logical threads per physical core and the Core i7-820QM 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 i7-4810MQ 4-Core and Core i7-820QM 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 i7-4810MQ 4-Core has a 1.07 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 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 Core i7-4810MQ 4-Core and the Core i7-820QM 4-Core have the same L2 cache size, but the Core i7-820QM 4-Core has a 2 MB bigger L3 cache, so in this area, it wins out over the Core i7-4810MQ 4-Core.

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 Core i7-820QM 4-Core has a 2 Watt lower Maximum TDP than the Core i7-4810MQ 4-Core. However, the Core i7-4810MQ 4-Core was created with a 23 nm smaller manufacturing technology. Overall, by taking both into account, the Core i7-4810MQ 4-Core is likely the CPU with the lower heat production and power requirements, by quite a wide margin.

The Core i7-4810MQ 4-Core 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 Core i7-820QM 4-Core, 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 ReviewCore i7-4810MQ 4-Core 2.8GHz is a high-end mobile processor based on the 22nm, Haswell microarchitecture.

It offers 4 Physical Cores (8 Logical), initially clocked at 2.8GHz, which may go up to 3.8GHz and 6MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost and Virtualization are activated.

The processor integrates powerful Graphics called Intel HD Graphics 4600, 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.
Both the processor and integrated graphics have a rated board TDP of 57W.

Its performance is exceptional. Therefore, it can be paired with even the most powerful dedicated graphics.
Core i7-820QM 4-Core 1.73GHz is a high-end mobile CPU based on the 45nm, Nehalem architecture.

It offers 4 Physical Cores (8 Logical), initially clocked at 1.73GHz, which may go up to 3.06GHz and 6MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost and Virtualization are activated.

The processor DOES NOT integrated any graphics and has a rated board TDP of 45W.

It offers average performance. This means it will become a bottleneck in some demanding applications.
