In terms of overall gaming performance, the Intel Celeron Dual-Core 867 1.3GHz is marginally better than the Intel Core i3-U380 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 Celeron Dual-Core 867 was released less than a year after the Core i3-U380 1.33GHz, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Core i3-U380 1.33GHz and the Celeron Dual-Core 867 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 Core i3-U380 1.33GHz and the Celeron Dual-Core 867 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 Core i3-U380 1.33GHz and Celeron Dual-Core 867 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 i3-U380 1.33GHz has a 0.03 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 Core i3-U380 1.33GHz and the Celeron Dual-Core 867 have the same L2 cache size, but the Core i3-U380 1.33GHz has a 1 MB bigger L3 cache, so in this area, it wins out over the Celeron Dual-Core 867.

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 Dual-Core 867 has a 1 Watt lower Maximum TDP than the Core i3-U380 1.33GHz, and was created with a 13 nm smaller manufacturing technology. What this means is the Celeron Dual-Core 867 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 ReviewCore i3-U380 1.33GHz is an entry-level mobile CPU based on 45nm architecture, Arrandale.
Just like all Arrandale based i3 processors, it offers 3MB of L3 Cache and integrated graphics called GMA 5700MHD (perhaps also known as just Intel HD Graphics). However, it's optimized for low power consumption, whereas the graphics are only clocked at 166MHz (against 500MHz of 380M, for example) and the cores are clocked at 1.33GHz only.
Its performance is below the average, considering today's standards. However, it offers great overclock potential, if the laptop's PSU allows it.
Sandy Bridge is the codename for a microarchitecture developed by Intel beginning in 2005 for central processing units in computers to replace the Nehalem microarchitecture. Intel demonstrated a Sandy Bridge processor in 2009, and released first products based on the architecture in January 2011 under the Core brand.
