In terms of overall gaming performance, the Intel Core i7-1065G7 4-Core 1.30GHz is massively better than the Intel Core i3-5005U 2.0GHz 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 i7-1065G7 4-Core was released over three years more recently than the Core i3-5005U 2.0GHz, and so the Core i7-1065G7 4-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Core i3-5005U 2.0GHz when running the latest games.

The Core i7-1065G7 4-Core has 2 more cores than the Core i3-5005U 2.0GHz. With 4 cores, the Core i7-1065G7 4-Core is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

The Core i7-1065G7 4-Core has 4 more threads than the Core i3-5005U 2.0GHz. Both the Core i7-1065G7 4-Core and the Core i3-5005U 2.0GHz use hyperthreading. The Core i7-1065G7 4-Core has 2 logical threads per physical core and the Core i3-5005U 2.0GHz 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 i7-1065G7 4-Core and Core i3-5005U 2.0GHz 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 i3-5005U 2.0GHz has a 0.7 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 Core i7-1065G7 4-Core.

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.

Both the Core i7-1065G7 4-Core and the Core i3-5005U 2.0GHz have the same TDP of 15 Watts, but the Core i7-1065G7 4-Core has a lower lithography size, and so will affect your yearly electricity bills less adversely.

The Core i7-1065G7 4-Core and the Core i3-5005U 2.0GHz both have an on-board GPU, which means that they will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card.

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 Core i7-1065G7 4-Core 1.30GHz is a CPU based on a refinement of the 14nm++ Comet Lake-S microarchitecture. It offers 4 physical cores (8 logical), initially clocked at 1.30 GHz, which may go up to 3.90 GHz using 4 cores with Turbo Boost. The Core i7-1065G7 has 8MB of L3 Cache.Broadwell is the codename for the Intel processor family that is the successor to the Haswell processor family and will be built on Intelís 14nm manufacturing process. Most Broadwell products are targeted at the 2 in 1 and notebook market but there will also be versions for desktop and server platforms. Broadwell delivers significant performance advancements over the prior generation, including improved graphics, power efficiency/battery life, and security.
