Conclusion
Last
summer we published a similar series of articles, where we were analyzing gaming
performance on the basis of two different processors. Back in the days it became
very clear that performance differences between two CPU's at high resolutions
are close to zero. The reason for this can be found within the fact, that the
processor isn't the bottleneck of a system, when you're playing games at high
resolutions. In this case it's the graphics card, which has to work overtime. In
case of lower resolutions the influence of the processor becomes clearly
visible, since the graphics card isn't the limiting factor anymore.
Having a closer look at the results we gathered while testing eight different
games and two different benchmarks with two different presets, we see that the
Core i7-4770K, with our "low-preset" is on average 4.7 percent faster than the
Core i7-3770K. Switching to our "high-preset" makes the Core i7-4770K's
become 0.41 percent slower than the Core i7-3770K. We wouldn't emphasize this
point too much and start yelling, that an old processor is faster than a new
one, since a 0.41 percent advantage is most likely within the measurement error. Overclocking the Core i7-4770K to 4.5 GHz makes the performance
with our "low-preset" go up by 11 percent but when it comes to the high-preset
the increase in performance is only 1 percent. Regarding the Core i7-3770K the
situation is similar: 11.7 percent gain with "low-preset" and 0.8 percent
with "high-preset".
What's quite interesting to see is how the wattage of our test system increased
while maintaining 4.5 GHz stably. The 4770K needed 40 percent more power and in case of the
3770K the increase was 30 percent.
If you bought a Core i7-3770K a while back, then we can tell you without the
shadow of a doubt, that there is absolutely no need to get rid of it and replace
it with a Core i7-4770K. From a gaming performance point of view it really doesn't matter
which of the two CPU's you have in your system. Apart from this, we found
that in Switzerland there is almost no price difference between the i7-3770K and
the 4770K but when you compare prices of these to CPU's in Europe you see that
the Core i7-3770K goes for 50 Euro less. Should be planning to upgrade your rig
with a CPU that supports HT and eight virtual threads and should you be situated
in a country, where the 3770K goes for less than the 4770K, then recommend to go
for the 3770K. In the end it's not only the CPU that is cheaper, you can also
get great Z77 board for less than their Z87 counterparts.
