Intel Core i5-10400 compared with i5-9400F, is it worth?

Imgur

Intel recently announced its new Comet Lake-S desktop CPUs and someone has already shared some benchmark figures that give us a hint of what we can expect from the Intel Core i5-10400.

Specs

Intel Core i5-10400 Intel Core i5-9400F
Cores / Threads 6 / 12 6 / 6
Base Clock 2.9 GHz 2.9 GHz
Boost Clock 4.3 GHz 4.1 GHz
Cache 12MB 9MB
TDP 64W 65W
iGPU UHD 630 @ 1.1 GHz None

Benchmark Results

The leaker, known as 尾随至幻城, reportedly used the new i5-10400 in MSI MAG Z490 Tomahawk motherboard with 16GB of DDR4 RAM and an Nvidia GeForce RTX 2070 to run benchmarks. This was compared to the Intel Core i5-9400F.

In single-threaded applications, the new Comet Lake chip gains performance increase of just 4-8% as compared to the 9th Gen Coffee Lake chip. However, in multi-threaded tests the i5-10400 performed better with improvements of up to 45%. The new Comet Lake i5-10400 comes with a 200 MHz higher boost clock, a little more L3 cache, and has Hyper-Threading, so that it can handle threaded workloads better. Otherwise, the two chips are nearly identical, except that the 9400F doesn’t have integrated graphics (iGPU) and drops into an older CPU socket. We weren’t expecting groundbreaking differences from Intel’s new CPUs in the mid-segment. It’s at the high-end where Intel is pushing the thermals to their absolute limits.
