In terms of overall gaming performance, the Intel Celeron D 347 is marginally better than the Intel Celeron D 320 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 D 347 was released over a year more recently than the Celeron D 320, and so the Celeron D 347 is likely to have better levels of support, and will be more optimized for running the latest games.

Both CPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful CPUs. Neither of these will be able to run the latest games in any playable way.

The Celeron D 347 and the Celeron D 320 both have 1 cores, and so are quite likely to struggle with the latest games, or at least bottleneck high-end graphics cards when running them. With a decent accompanying GPU, the Celeron D 347 and the Celeron D 320 may still be able to run slightly older games fairly effectively.

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 D 347 and the Celeron D 320 are from the same family of CPUs, and thus their clock speeds are directly comparable. With this in mind, it is safe to say that with a 0.66 GHz faster base clock rate, the Celeron D 347 manages to provide significantly better performance than the Celeron D 320.

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 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 D 320 has a 13 Watt lower Maximum TDP than the Celeron D 347 (though they were created with the same size 0 nm manufacturing technology). What this means is the Celeron D 320 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 ReviewBased on the Cedar Mill Pentium 4 core, this version of the Celeron D was launched 28 May 2006,and continued the 3xx naming scheme with the Celeron D 347 (3.06 GHz), 352 (3.2 GHz), 356 (3.33 GHz), 360 (3.46 GHz), and 365 (3.6 GHz). The Cedar Mill Celeron D is largely the same as the Prescott-256, except with double the L2 cache (512 KB) and based on a 65 nm manufacturing process. The Cedar Mill-512 Celeron D is LGA 775 exclusive. The main benefits of the Cedar Mill Celerons over the Prescott Celerons are the slightly increased performance due to the larger L2 cache, higher clock rates, and less heat dissipation, with several models having a TDP lowered to 65 W from Prescott's lowest offering of 73 W.Celeron D 320 is a cheap CPU with very limited performance (only one core) and high power consumption.
The performance isn't enough to play most of today's games at decent settings.
