Gaming Performance Comparison

In terms of overall gaming performance, the Intel Core i7-4770 4-Core 3.4GHz is noticeably better than the Intel Core i7-3770 4-Core 3.4GHz 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 i7-4770 4-Core was released over a year more recently than the Core i7-3770 4-Core, and so the Core i7-4770 4-Core is likely to have better levels of support, and will be more optimized for running the latest games.

Both CPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings (assuming they are accompanied by equivalently powerful GPUs).

The Core i7-4770 4-Core and the Core i7-3770 4-Core both have 4 cores, which is not likely to be a limiting factor for gaming.

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 i7-4770 4-Core and Core i7-3770 4-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 Core i7-4770 4-Core and the Core i7-3770 4-Core both have the same clock frequency, this is by no means an indicator that the two CPUs will provide the same level of performance. 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 i7-4770 4-Core and the Core i7-3770 4-Core have the same L2 cache size, and the same L3 cache size, so in terms of cache-related gaming performance, the two CPUs are practically identical.

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 i7-3770 4-Core has a 7 Watt lower Maximum TDP than the Core i7-4770 4-Core (though they were created with the same size 22 nm manufacturing technology). What this means is the Core i7-3770 4-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 i7-4770 4-Core and the Core i7-3770 4-Core both have an on-board GPU, which means that they will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card.

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 i7-4770 4-Core 3.4GHz is a high-end CPU based on the 22nm Haswell architecture.
It packs 4 physical Cores (8 logical) initially clocked at 3.4GHz whose frequencies will go up to 3.9GHz in Single Mode. The max power drawn is of 84W.
It features integrated graphics called Intel HD 4600 that can have the central unit clocked up to 1200MHz (in Turbo Mode) and the fastest memory supported is DDR3-1600.
Paired with the appropriate graphics card, even the most demanding games will run at the highest settings.
This powerful Ivy Bridge CPU can be compared with the older Sandy Bridge i7-2700K, which can already be called 'A Ferrari under the CPUs' and has the unlocked multiplier (K-model)! Just like the 2700K, it can provide a turbo frequency of 3.9GHz at 1 core. The only difference between this one and the 3770K, is the 0.1GHz lower clock frequency at stock, but this one has little overclock possibilities due to the locked multiplier!
