In terms of overall gaming performance, the Intel Celeron G1820 2.7GHz is marginally better than the AMD Opteron 8374 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 Celeron G1820 2.7GHz was released over three years more recently than the Opteron 8374 HE, and so the Celeron G1820 2.7GHz is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Opteron 8374 HE when running the latest games.

The Opteron 8374 HE has 2 more cores than the Celeron G1820 2.7GHz. With 4 cores, the Opteron 8374 HE is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

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 Celeron G1820 2.7GHz and Opteron 8374 HE 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 Celeron G1820 2.7GHz 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 Opteron 8374 HE.

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 Celeron G1820 2.7GHz and the Opteron 8374 HE have the same L2 cache size, but the Opteron 8374 HE has a 6142 MB bigger L3 cache, so in this area, it wins out over the Celeron G1820 2.7GHz.

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 Celeron G1820 2.7GHz has a 2 Watt lower Maximum TDP than the Opteron 8374 HE, and was created with a 23 nm smaller manufacturing technology. What this means is the Celeron G1820 2.7GHz will consume slightly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill slightly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewCeleron G1820 2.7GHz is a budget dual Core Processor based on the 22nm Haswell architecture.
It succeeds the Ivy Bridge Celeron G1620 Dual-Core 2.7GHz and against it, it remains within the same TDP and it offers superior CPU performance though the integrated graphics are still weak, very weak actually and doomed as soon as they star to run any 3D game.
Opteron is AMD's x86 server and workstation processor line, and was the first processor which supported 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 Piledriver-based Opteron 4300 and 6300 series processors, codenamed "Seoul" and "Abu Dhabi" respectively.
