In terms of overall gaming performance, the Intel Core i3-4370 3.8GHz is very slightly better than the AMD Phenom II X4 B65 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 i3-4370 3.8GHz was released less than a year after the Phenom II X4, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

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 Phenom II X4 has 2 more cores than the Core i3-4370 3.8GHz. With 4 cores, the Phenom II X4 is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

Both the AMD Phenom II X4 B65 and the Intel Core i3-4370 3.8GHz have the same number of threads. The Phenom II X4 has one thread per physical core, whereas the Core i3-4370 3.8GHz 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 Phenom II X4 and Core i3-4370 3.8GHz 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 i3-4370 3.8GHz has a 0.4 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 Phenom II X4.

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 Phenom II X4 has a 1536 KB bigger L2 cache than the Core i3-4370 3.8GHz, which means that it, at worst, wins out in this area, and at best, will provide superior gaming performance and will work much better with high-end graphics cards.

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 i3-4370 3.8GHz has a 41 Watt lower Maximum TDP than the Phenom II X4, and was created with a 23 nm smaller manufacturing technology. What this means is the Core i3-4370 3.8GHz will consume significantly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill significantly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

The Core i3-4370 3.8GHz 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 Phenom II X4, 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 ReviewPhenom II X4 B65 is an unlocked Phenom II X2 565.

It should offer similar performance to a Phenom II X4 B99.
Core i3-4370 3.8GHz is a middle-class CPU based on the 22nm, Haswell architecture.

It offers 2 Physical Cores (4 Logical), clocked at 3.8GHz and 4MB of L3 Cache.
Among its many features, Turbo Boost and HyperThreading are activated.

The processor integrates powerful Graphics called Intel HD Graphics 4600, with 20 Execution Units, initially clocked at 350MHz and that go up to 1150MHz, 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 54W.

It is a powerful processor whose performance is good. It's thus capable of running most applications smoothly without any problem.
