In terms of overall gaming performance, the Intel Pentium Dual Core 3561Y 1.2GHz is marginally better than the Intel Pentium U5600 1.33GHz 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 Dual Core was released over a year more recently than the Pentium U5600 1.33GHz, and so the Pentium Dual Core is likely to have better levels of support, and will be more optimized for running the latest games.

The Pentium Dual Core and the Pentium U5600 1.33GHz both have 2 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 Pentium Dual Core and the Pentium U5600 1.33GHz 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 Pentium Dual Core and Pentium U5600 1.33GHz 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 U5600 1.33GHz has a 0.13 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. 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 Pentium Dual Core has a 512 KB bigger L2 cache than the Pentium U5600 1.33GHz, but on the other hand, it is the Pentium U5600 1.33GHz that has a 1 MB bigger L3 cache than the Pentium Dual Core.

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 Dual Core has a 6 Watt lower Maximum TDP than the Pentium U5600 1.33GHz, and was created with a 10 nm smaller manufacturing technology. What this means is the Pentium Dual Core 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 ReviewHaswell is the codename for a processor microarchitecture developed by Intel as the successor to the Ivy Bridge architecture. It uses the 22 nm process. Intel officially announced CPUs with this microarchitecture on June 4, 2013 at Computex Taipei 2013. With Haswell, Intel introduced a low-power processor designed for convertible or 'hybrid' Ultrabooks, having the Y suffix. Intel demonstrated a working Haswell chip at the 2011 Intel Developer Forum.Arrandale is the code name for a mobile Intel processor, sold as mobile Intel Core i3, i5 and i7 as well as Celeron and Pentium. It is closely related to the desktop Clarkdale processor; both use dual-core dies based on the 32 nm Westmere shrink of the Nehalem microarchitecture and have integrated Graphics as well as PCI Express and DMI links.
Arrandale is the successor of the 45 nm Core microarchitecture based Penryn processor that is used in the many mobile Intel Core 2, Celeron and Pentium Dual-Core processors. While Penryn typically used both a north bridge and a south bridge, Arrandale already contains the major north bridge components, which are the memory controller, PCI Express for external graphics, integrated graphics and the DMI connector, making it possible to build more compact systems without a separate northbridge or discrete graphics as Lynnfield.
