In terms of overall gaming performance, the AMD APU A10-7700k Quad-Core is marginally better than the Intel Core i3-3240 3.4GHz 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 APU A10-7700k Quad-Core was released over a year more recently than the Core i3-3240 3.4GHz, and so the APU A10-7700k Quad-Core is likely to have better levels of support, and will be more optimized for 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 APU A10-7700k Quad-Core has 2 more cores than the Core i3-3240 3.4GHz. With 4 cores, the APU A10-7700k Quad-Core is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

Both the AMD APU A10-7700k Quad-Core and the Intel Core i3-3240 3.4GHz have the same number of threads. The APU A10-7700k Quad-Core has one thread per physical core, whereas the Core i3-3240 3.4GHz 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 APU A10-7700k Quad-Core and Core i3-3240 3.4GHz 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 APU A10-7700k Quad-Core and the Core i3-3240 3.4GHz both have the same clock frequency, this is by no means an indicator that the two CPUs will provide the same level of performance. As such, we need to look elsewhere for more reliable comparisons.

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 APU A10-7700k Quad-Core has a 3584 KB bigger L2 cache than the Core i3-3240 3.4GHz, and although the APU A10-7700k Quad-Core 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 i3-3240 3.4GHz has a 40 Watt lower Maximum TDP than the APU A10-7700k Quad-Core, and was created with a 6 nm smaller manufacturing technology. What this means is the Core i3-3240 3.4GHz 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 APU A10-7700k Quad-Core and the Core i3-3240 3.4GHz 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.

For an in-depth GPU comparison, click on the GPU comparison icon that you can find throughout Game-Debate:

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 ReviewAPU A10-7850K Quad-Core is a performance CPU based on the 28nm, Steamroller architecture.

It offers 4 Physical Cores (4 Logical), initially clocked at 3.4GHz, which may go up to 3.8GHz and 4MB of L2 Cache.
Among its many features, Turbo Core and Virtualization are activated and the processor has the clock multiplier unlocked, meaning it can be overclocked easily.

The processor integrates powerful Graphics called Radeon R7 7700K, with 384 Shader Processing Units, clocked at 720MHz, which share the L2 Cache and system RAM with the processor.
Both the processor and integrated graphics have a rated board TDP of 95W.

It is a powerful Quad Core whose performance is good. It's thus capable of running most applications smoothly without any problem.
Core i3-3240 3.4GHz is a middle-class CPU based on the 22nm, Ivy Bridge architecture.

It offers 2 Physical Cores (4 Logical), clocked at 3.4GHz and 3MB of L3 Cache.
Among its many features, Turbo Boost and HyperThreading are activated.

The processor integrates relatively weak Graphics called Intel HD Graphics 2500, with 6 Execution Units, initially clocked at 650MHz and that go up to 1050MHz, 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 55W.
