In terms of overall gaming performance, the Intel Pentium G3460 3.5GHz is marginally better than the Intel Core 2 Extreme QX6850 3.0GHz 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 Pentium G3460 3.5GHz was released over three years more recently than the Core 2 Extreme, and so the Pentium G3460 3.5GHz is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Core 2 Extreme 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 Core 2 Extreme has 2 more cores than the Pentium G3460 3.5GHz. With 4 cores, the Core 2 Extreme is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

The Core 2 Extreme has 2 more threads than the Pentium G3460 3.5GHz. Both CPUs have one thread 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 Pentium G3460 3.5GHz and Core 2 Extreme 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 Pentium G3460 3.5GHz has a 0.5 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 2 Extreme.

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 2 Extreme has a 7680 KB bigger L2 cache than the Pentium G3460 3.5GHz, and although the Core 2 Extreme 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 Pentium G3460 3.5GHz has a 77 Watt lower Maximum TDP than the Core 2 Extreme, and was created with a 43 nm smaller manufacturing technology. What this means is the Pentium G3460 3.5GHz 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 Pentium G3460 3.5GHz 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 Core 2 Extreme, 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 ReviewPentium G3460 3.5GHz is a budget processor based on the 22nm, Haswell architecture.

It offers 2 Physical Cores (2 Logical), clocked at 3.5GHz and 3MB of L3 Cache.
Among its many features, Virtualization is activated.

The processor integrates very weak Graphics called Intel HD Graphics Desktop (Haswell), with 10 Execution Units, initially clocked at 350MHz and that go up to 1100MHz, 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.
Core 2 Extreme QX6850 3.0GHz is a performance Processor based on the 65nm Core micro-architecture.

It offers 4 Physical Cores (4 Logical), clocked at 3.0GHz and 8MB of L2 Cache.
Among its many features, Virtualization is activated.

The processor DOES NOT integrate any graphics. and has a rated board TDP of 130W.

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