In terms of overall gaming performance, the Intel Core i3-7101E 2-Core 3.9GHz is massively better than the AMD Athlon 64 1640B 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 Athlon 64 1640B was released less than a year after the Core i3-7101E 2-Core, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Core i3-7101E 2-Core has 1 more core than the Athlon 64 1640B. However, while the Core i3-7101E 2-Core will probably perform better than the Athlon 64 1640B, both CPUs are likely to struggle with the latest games, and will almost certainly bottleneck high-end graphics cards. This should not affect games that are a few years old, and even the latest games should at least be playable on very low settings, as only recently have game developers begun to harness the power of multiple cores.

The Core i3-7101E 2-Core has 3 more threads than the Athlon 64 1640B. The Athlon 64 1640B has one thread per physical core, whereas the Core i3-7101E 2-Core uses hyperthreading and has 2 logical threads per physical core.

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 i3-7101E 2-Core and Athlon 64 1640B 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 i3-7101E 2-Core has a 1.2 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 Core i3-7101E 2-Core 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 i3-7101E 2-Core and the Athlon 64 1640B have the same L2 cache size, but the Athlon 64 1640B does not appear to have an L3 cache, so the Core i3-7101E 2-Core definitely 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 Athlon 64 1640B has a 9 Watt lower Maximum TDP than the Core i3-7101E 2-Core. However, the Core i3-7101E 2-Core was created with a 51 nm smaller manufacturing technology. Overall, by taking both into account, the Core i3-7101E 2-Core is likely the CPU with the lower heat production and power requirements, by quite a wide margin.

CPU Mini Review

Mini ReviewThe Core i3-7101E 2-Core 3.9GHz is a Middle-Class CPU based on Intel's 7th Gen 14nm, Kaby Lake microarchitecture. It offers 2 physical cores (4 logical), clocked at 3.9GHz. It doesn't have an unlocked multiplier therefore it can't be overclocked using traditional methods. It has 3MB 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 54W. It is on par with competitor processors. Among its many features, Intel Enhanced Speedstep, HyperThreading and Virtualization are activated. It integrates Intel HD Graphics 630 on board. It has a base frequency of 350MHz which can go up to 1GHz as well as offering DirectX 12 support. This CPU is likely to offer good computational performance but may suffer from performance dips on higher resolutions and demanding applications.Athlon 64 1640B is an entry-level Processor based on the 65nm K8 micro-architecture.

It offers 1 Physical Core (1 Logical), clocked at 2.7GHz and 1MB of L2 Cache.
Among its many features, Virtualization is activated.

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

Its performance is below the average and so most demanding games will not run optimally.
