Gaming Performance Comparison

In terms of overall gaming performance, the Intel Core i5-3340M 2.7GHz is noticeably better than the Intel Core i7-4500U 2-Core 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 i7-4500U 2-Core was released less than a year after the Core i5-3340M 2.7GHz, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Core i7-4500U 2-Core and the Core i5-3340M 2.7GHz 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 i7-4500U 2-Core and the Core i5-3340M 2.7GHz 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 i7-4500U 2-Core and Core i5-3340M 2.7GHz 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 i5-3340M 2.7GHz has a 0.9 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 i7-4500U 2-Core and the Core i5-3340M 2.7GHz have the same L2 cache size, but the Core i7-4500U 2-Core has a 1 MB bigger L3 cache, so in this area, it wins out over the Core i5-3340M 2.7GHz.

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 i7-4500U 2-Core has a 20 Watt lower Maximum TDP than the Core i5-3340M 2.7GHz (though they were created with the same size 22 nm manufacturing technology). What this means is the Core i7-4500U 2-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).

The Core i7-4500U 2-Core has an on-board GPU, which means that it will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card. The Core i5-3340M 2.7GHz, however, does not, and you will probably have to look for a dedicated card if you wish to use it at all.

On-board GPUs tend to be fairly awful in comparison to dedicated cards from the likes of AMD or Nvidia, but as they are built into the CPU, they also tend to be cheaper and require far less power to run (this makes them a good choice for laptops). We would recommend a dedicated card for running the latest games, but integrated GPUs are improving all the time and casual gamers may find less recent games perform perfectly acceptably.

CPU Mini Review

Mini ReviewCore i7-4500U 1.8GHz is a mobile Dual Core microprocessor, based on the 22nm Haswell core. The core frequency goes up to 3.0GHz in Turbo mode, and the integrated GPU reaches 1.1GHz, whilst it is initially clocked at 200MHz. The Thermal Design Power should not exceed that of 15 watts, a standard power draw characteristic to mobile CPUs. The price at which this CPU will come will also depend on the other components of the Laptop that features this processor.Core i5-3340M 2.7GHz is a middle-class mobile processor based on the 22nm Ivy Bridge architecture with almost all of the Ivy Bridge features activated.
It features 2 Cores (4 Threads), clocked at 2.7GHz which will go up to 3.4GHz (single mode) and 3.2GHz (dual mode) and integrated graphics called Intel HD 4000 which run at 650MHz (1250 MHz in Turbo mode). The CPU supports DDR3-1600 and DDR3L-1600 memory types. Expect a TDP of up to 35 Watts.
This CPU's rank is predicted and will be updated once benchmarks become available.
