Intel Core i3-8350K CPU Performance Leaks Out – Multi-Threading Performance Almost on Par With A Core i7-7700K, Single-Thread Results Shows IPC Lead

Aug 23, 2017

The first detailed benchmarks of Intel’s Core i3-8350K Coffee Leak processor have just leaked out. The Intel Core i3-8350K will be the first Core i3 branded chip to feature a quad core design that is going to deliver faster performance in multi-tasking compared to last generation i3 chips.

Intel Core i3-8350K Quad Core Coffee Lake CPU Performance Leaked – Faster in Single Threading, Almost on par in Multi-Threading Compared To Previous Generation Flagship i7

Intel announced their 8th generation processors a few days ago. The lineup revealed that Intel’s 8th generation family will be a mixture of different architectures. These will include Kaby Lake, Coffee Lake and Cannonlake chips. So we will be looking at 14nm+, 14nm++ and 10nm chips, all within a single family. The desktop processors will be based on the Coffee Lake architecture and first details were posted weeks ago over here.

While we got to see the performance of the flagship Core i7-8700K chip that rocks 6 cores and 12 threads, budget users would be more interested in the upcoming Core i3 processors. From the looks of it, the Core i3 series in the Coffee Lake desktop family will deliver great performance in single and multi-threading workloads. The improvements come from two things, a better process that allows for higher clock speeds, a fine tuned architecture that is built on the foundation of Kaby Lake and lastly, increase in core count.

The Intel Core i3-8350K will be the only Core i3 chip in the 8th Gen family that enables overclocking support. Intel’s 8th Gen Core i3 family is also the first to feature 4 cores which will be a great deal for budget builders. The Intel Core i3 8350K comes with 4 cores and 4 threads that are clocked at 4.0 GHz. The chip features 8 MB of cache and will feature a TDP of 95W.

There’s also the Intel Core i3-8100 which is a 4 core, non-multi threaded SKU. This chip has a lower clock speed of 65W and features a clock speed of 3.6 GHz. There’s a total of 6 MB of L3 cache on the processor itself which confirms the exclusion of multi-threading. The Intel Core i3 chips will not feature boost clocks but they will have a more stable base clock speed and we can expect prices of the chips to be in the sub-$200 US range.

Coming to the benchmarks, we will first be looking at the CPU-Z benchmark where the Core i3-8350K scores 503.3 points in single threaded and 1982.0 points in multi-threaded benchmarks. Comparing the single-threaded score, we can see that the Core i3-8350K is faster than the Intel Core i7-7700K which does 492 points with a higher rated clock speed of 4.2 GHz base and 4.5 GHz boost while the i3 only boasts a 4.0 GHz clock. In multi-threading, the Core i7-7700K scores 2648 points but we can see that it is solely due to the higher thread count and within the range that i3 can easily overcome with a slight overclock.

The Intel Core i7-6700K which shipped at similar base clocks of 4.0 GHz (4C/8T) has a single core score of 474 and multi-thread score of 2377. Both tests make the Core i3-8350K look like a very compelling budget tier chip, especially when it will be able to match last gen Core i7’s under a price bracket of $200 US.

Moving forward, we have several tests from the AIDA64 internal benchmarking utility. The chip was tested on a Z370 motherboard and due to lack of support, there are labels that don’t show up right now as correct. The benchmarks can be seen below and once again, we see a lead in CPU and RAM (DDR4) performance on the Core i3-8350K chip compared to the Core i7-6700K processor.

If Intel manages to adjust the prices to be more budget friendly, we can see a good response to their upcoming 8th Generation core family on the desktop platform. Launch is expected in the first week of October so look forward to more news in the coming days.
