Let’s talk a bit about the Core i3-10100.
The same UHD Graphics 630 are in use, and we’re looking at a 65 W TDP rating.
Thus the only performance advantage seen in more expensive Z490 motherboards will be through memory overclocking.

Using the included box cooler it peaked at just 61C in our Blender stress test and ran reasonably quiet.
The smaller L3 cache will also contribute for some of that margin.
The 7-zip compression results look quite similar to Cinebench multi-core.
We’re also looking at a further 5% decline in performance when using the slower DDR4-2666 memory.
Moving over to decompression performance, we see similar results for the 10100 using either DDR4-2666 or 3200 memory.
Here’s a look at AES-256 multi-thread performance.
That improvement is overshadowed by the fact that the 3300X is still over 20% faster.
The Core i3-10100 managed to match the Core i7-7700K in the DaVinci Resolve Studio 16 benchmark.
Not big margins as before, but the trend of Ryzen 3 winning on the productivity side continues.
Surprisingly though the 3300X was still 17% faster.
TL;DR: we don’t believe in testing CPUs without a strong GPU bottleneck.
The 10100 is able to roughly match the 7700K when paired with DDR4-3200 memory.
Next up we have Far Cry New Dawn.
Moving to 1440p shows the 10100 is only able to match the 9100F.
Both operate at similar clock speeds but we’ve seen many instances where Hyper-Threading can hamper gaming performance.
Gears Tactics results has the i3-10100 performing slower than the 7700K again.
But even so, we’re looking at gaming performance where the 3300X is some 16% faster.
The margins seen in Rainbow Six Siege don’t paint a nice picture for the i3-10100 either.
Here the 3300X was 21% faster when comparing 1% low data.
Even at 1440p the 3300X was still 7% faster when comparing 1% low data.
The i3-10100 still trailed the 3300X at 1440p.
Here the Ryzen chip was 9% faster when comparing the DDR4-3200 configurations.
Red Dead Redemption 2 shows subpar performance for the Core i3-10100 when compared to the R3 3300X.
On this board the 10100 performs exactly like the DDR4-2666 configuration just shown.
Not thermally limited, not going to make any difference to the benchmarks.
As for the Core i3-10100, what do we make of it?
Coming inat $120, that’s the same price as the 3300X.
Thus, the 10100 makes sense and can be a more cost effective option for some.
