In terms of overall gaming performance, the Intel Core i7-2700K 4-Core 3.50GHz is massively better than the AMD Opteron 4274 HE 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 Opteron 4274 HE was released less than a year after the Core i7-2700K 4-Core, 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 Opteron 4274 HE has 4 more cores than the Core i7-2700K 4-Core. 8 cores is probably excessive if you mean to just run the latest games, as games are not yet able to harness this many cores. The cores in the Core i7-2700K 4-Core is more than enough for gaming purposes. However, if you intend on running a server with the Opteron 4274 HE, it would seem to be a decent choice.

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 Opteron 4274 HE and Core i7-2700K 4-Core 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 i7-2700K 4-Core has a 1 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 Opteron 4274 HE 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 i7-2700K 4-Core has a 24 KB bigger L2 cache than the Opteron 4274 HE, and the two CPUs have the same L3 cache size, so the Core i7-2700K 4-Core wins out in this area with its larger L2 cache.

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 Opteron 4274 HE has a 30 Watt lower Maximum TDP than the Core i7-2700K 4-Core (though they were created with the same size 32 nm manufacturing technology). What this means is the Opteron 4274 HE 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 i7-2700K 4-Core 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 Opteron 4274 HE, 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 ReviewOpteron is AMD's x86 server and workstation processor line, and was the first processor to implement the AMD64 instruction set architecture (known generically as x86-64). It was released on April 22, 2003 with the SledgeHammer core (K8) and was intended to compete in the server and workstation markets, particularly in the same segment as the Intel Xeon processor. Processors based on the AMD K10 microarchitecture (codenamed Barcelona) were announced on September 10, 2007 featuring a new quad-core configuration. The most-recently released Opteron CPUs are the 8- and 12-core Socket G34 Opterons, code-named Magny-Cours.Core i7-2700K 4-Core 3.5GHz is a high-end CPU based on the 32nm, Sandy Bridge architecture.

It offers 4 Physical Cores (8 Logical), initially clocked at 3.5GHz, which may go up to 3.9GHz and 8MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost and Virtualization are activated and the processor has unlocked multiplier.

The processor integrates average Graphics called Intel HD i7 2700K (variant of Intel HD Graphics 3000), with 12 Execution Units, initially clocked at 850MHz and that go up to 1350MHz, 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 95W.

Its performance is exceptionally good and enough for even the most demanding applications.
