In terms of overall gaming performance, the Intel Core i5-670 3.46GHz is massively better than the AMD Athlon II X3 445 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 II X3 was released less than a year after the Core i5-670 3.46GHz, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Athlon II X3 has 1 more core than the Core i5-670 3.46GHz. However, while the Athlon II X3 will probably perform better than the Core i5-670 3.46GHz, 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.

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 Athlon II X3 and Core i5-670 3.46GHz 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 i5-670 3.46GHz has a 0.36 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 Athlon II X3.

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 Athlon II X3 has a 1024 KB bigger L2 cache than the Core i5-670 3.46GHz, and although the Athlon II X3 does not appear to have an L3 cache, its larger L2 cache means that it 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 Core i5-670 3.46GHz has a 22 Watt lower Maximum TDP than the Athlon II X3, and was created with a 13 nm smaller manufacturing technology. What this means is the Core i5-670 3.46GHz 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 i5-670 3.46GHz 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 Athlon II X3, 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 ReviewThe Athlon II series is based on the AMD K10 architecture and derived from the Phenom II series. However, unlike its Phenom siblings, it does not contain any L3 Cache. There are two Athlon II dies: the dual-core Regor die with 1 MB L2 Cache per core and the four-core Propus with 512 KB per core. Regor is a native dual-core design with lower TDP and additional L2 to offset the removal of L3 cache. The three core Rana is derived from the Propus quad-core design, with one core disabled. They say that also this one can be unlocked to the Phenom II X4 B45, just like the Phenom II X2 545 CPU.Core i5-670 3.46GHz is a performance CPU based on the 45nm, Nehalem architecture.

It offers 2 Physical Cores (4 Logical), initially clocked at 3.46GHz, which may go up to 3.73GHz and 4MB of L3 Cache.
Among its many features, Hyper-Threading, Turbo Boost and Virtualization are activated.

The processor integrates very weak Graphics called Intel i5 670, with XX Execution Units, clocked at 733MHz which share the L2 Cache and system RAM with the processor.
Both the processor and integrated graphics have a rated board TDP of 73W.

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