In terms of overall gaming performance, the Intel Core i7-620UE 2-Core 1.06GHz is noticeably better than the Intel Core 2 Duo L9380 1.8GHz 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 Core i7-620UE 2-Core was released over a year more recently than the Core 2 Duo, and so the Core i7-620UE 2-Core is likely to have better levels of support, and will be more optimized for running the latest games.

The Core i7-620UE 2-Core and the Core 2 Duo 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 i7-620UE 2-Core and the Core 2 Duo 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 i7-620UE 2-Core and Core 2 Duo 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 2 Duo has a 0.74 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 probably a good indicator that the is superior.

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 2 Duo has a 5632 KB bigger L2 cache than the Core i7-620UE 2-Core, and although the Core 2 Duo does not appear to have an L3 cache, its larger L2 cache means that it wins out in this area.

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 Core 2 Duo has a 1 Watt lower Maximum TDP than the Core i7-620UE 2-Core. However, the Core i7-620UE 2-Core was created with a 13 nm smaller manufacturing technology. Overall, by taking both into account, the Core i7-620UE 2-Core is likely the CPU with the lower heat production and power requirements, by quite a wide margin.

CPU Mini Review

Mini ReviewCore 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.
Core 2 is a brand encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module. The introduction of Core 2 relegated the Pentium brand to the mid-range market, and reunified laptop and desktop CPU lines, which previously had been divided into the Pentium 4, Pentium D, and Pentium M brands.
The Core microarchitecture returned to lower clock rates and improved the usage of both available clock cycles and power when compared with the preceding NetBurst microarchitecture of the Pentium 4/D-branded CPUs. The Core microarchitecture provides more efficient decoding stages, execution units, caches, and buses, reducing the power consumption of Core 2-branded CPUs while increasing their processing capacity. Intel's CPUs have varied widely in power consumption according to clock rate, architecture, and semiconductor process, shown in the CPU power dissipation tables.
