We present the 8th generation of Intel Core processors, called Intel Coffee Lake. In particular, we will analyze the desktop version.
Coffee Lake is a real revolution, in fact the i3, i5 and i7 processors are structurally different (in terms of physical cores) from the previous ones and for the first time, we have 6 physical cores (+ 6 logical) on socket 1151.
But let’s see what changes:
- i3 have 4 physical cores but not hyperthreading against the 2 with hyperthreading of the Kaby Lake versionù
- i5 have 6 physical cores compared to 4 of the Kaby Lake version
- i7 have 6 physical cores with hyperthreading compared to 4 with hyperthreading of the Kaby Lake version
Also important is the increase in the cache:
- from 8MB to 12MB for i7
- from 6MB to 9MB for i5
- from 3MB to 6MB for i3
These implementations lead, in terms of performance, to very interesting results without going to increase the tdp of the i5 and i7 processors.
We find, as in previous versions, processors with TDP of 65W and 35W, we do not consider the K versions to 95W as not embedded (with long availability).
Comparing the benchmark data this improvement appears evident.

Benchmark data comparison i3 7100 vs i3 8100
It is more interesting to compare the data related to the i3, i5 and i7 processors with 65W of tdp of the Kaby Lake family with those of the corresponding Coffee Lake processors but with TDP at 35W. Almost halving the TDP data, the 8th gen processors still perform better than the 7th gen processor.

Benchmark data comparison i3 7100 vs i3 8100T
The above data, the structural implementations in terms of the core and in general the evolution of the architectures show how important the knowledge of these is.
In Tpole we invest a lot of time in the study of architectures so that our commercial technicians can support you in a professional way in the correct sizing of the same.
