In terms of overall gaming performance, the Intel Core i7-620UE 2-Core 1.06GHz is noticeably better than the Intel Celeron 1007U 1.5GHz 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 1007U 1.5GHz was released over three years more recently than the Core i7-620UE 2-Core, and so the Celeron 1007U 1.5GHz is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Core i7-620UE 2-Core when running the latest games.

The Celeron 1007U 1.5GHz and the Core i7-620UE 2-Core 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 Celeron 1007U 1.5GHz and the Core i7-620UE 2-Core 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 1007U 1.5GHz and Core i7-620UE 2-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 Celeron 1007U 1.5GHz has a 0.44 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 .

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 1007U 1.5GHz and the Core i7-620UE 2-Core have the same L2 cache size, but the Core i7-620UE 2-Core has a 2 MB bigger L3 cache, so in this area, it wins out over the Celeron 1007U 1.5GHz.

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 1007U 1.5GHz has a 1 Watt lower Maximum TDP than the Core i7-620UE 2-Core, and was created with a 10 nm smaller manufacturing technology. What this means is the Celeron 1007U 1.5GHz 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 1007U 1.5GHz is an upcoming Ultra-low voltage-budget laptop CPU based on the Ivy Bridge micro-architecture.
Manufactured with a 22nm technology, it features 2 Cores clocked at 1.5GHz and Integrated Graphics initially clocked at 350MHz and that go up to 1000MHz in Turbo Mode. The Memory controller supports up to DDR3-1333 memory type. The Max power drawn should be of around 17W.
Its rank and specifications are predicted. Expect this CPU to be released in the first Quarter of 2013 and to deliver better performance than previous Sandy Bridge based Celeron B800E Series.
Core i7-620UE 2-Core 1.06GHz is an ultra energy efficient mobile CPU based on the 32nm, Nehalem architecture.

It offers 2 Physical Cores (4 Logical), initially clocked at 1.067GHz, which may go up to 2.133GHz and 4MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost and Virtualization are activated.

The processor integrates very weak Graphics called Intel HD i7 620UE, with 10 Execution Units, initially clocked at 166MHz and that go up to 500MHz, 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 18W.

Its performance is below the average and so most demanding games will not run optimally.
