Intel Core i7-9700K (Coffee Lake Refresh)
Intel Core i7-8700K (Coffee Lake)

Itching to get an idea of how the upcoming Intel Core i7-9700K processor will perform? You're in luck, as an anonymous individual appears to have submitted a 64-bit CPU benchmark to the public Geekbench database.

Before we dig into the results, a quick recap on what we know of the upcoming 9th Gen Core processors. Rumoured to be launching as soon as next month, the new CPUs go by the code name of 'Coffee Lake Refresh' and are expected to built on an optimised 14nm architecture that will herald the chip giant's first mainstream eight-core parts.

Championing the range will be the Core i9-9900K, an eight-core, 16-thread flagship with base and boost clocks of 3.6GHz and 5.0GHz, respectively. What's interesting this time around is that Intel appears to be using hyper-threading as a means of setting the Core i9 apart from the rest of the pack; our understanding is that K-Series Core i7 and Core i5 desktop CPUs will have the feature disabled, marking a surprise shift from previous generations.

In contrast to the current Core i7-8700K, which features six cores and 12 threads, the looming Core i7-9700K will be an eight-core, eight-thread part. Base clock will fall from 3.7GHz to 3.6GHz, while boost clock rises from 4.7GHz to 4.9GHz, but it will be interesting to see how the newcomer compares during real-world use given that it has two more physical cores but four fewer threads.

Geekbench isn't the test we typically turn to for high-end desktop CPUs, yet the early numbers do shed some light. In the screenshot (above, left) a Core i7-9700K returns a single-core score of 6,297 and a multi-core score of 30,152. To provide a comparison, we've run the same benchmark on our own Core i7-8700K test platform (above, right) and the results suggest that Coffee Lake Refresh is roughly five per cent quicker in a single-threaded scenario, and despite having fewer threads to work with, the eight physical cores deliver almost a 10 per cent boost in the multi-threaded test.

We're eager to see how the 9700K compares to AMD's eight-core, 16-thread Ryzen 7 2700X using our own benchmark suite, and we suspect we'll have the opportunity to find out soon, but in the meantime it seems Intel will continue to have the upper hand in the overclocking department. An earlier leak reportedly showed the Core i7-9700K hitting 5.5GHz with water-cooling, and now expreview reckons the chip will do 5.3GHz on air using just 1.215V. Either way, 2018 is turning out to be a fascinating year for CPU launches.

Wow call me shocked…. 8 real core are faster than 6 real cores plus 6 ‘fill in the gap’ hyperthreading cores….
I personally hope that Intel doesn't diferentiate the i7 and neglect the i5 platform too much. I was hoping to get one of the new i5 9600k'series and I have put off getting an i5 8600k because of the upcoming refresh.

If you'd expect 2 cores to beat 6 hyperthreads then those hyperthreads would be 30% as productive or worse. I'd hope, and have found, that a hyperthread provides a lot more than that, although it would depend on the application.

Hmm, I genuinely wouldn't be surprised to find that Intel's HT threads can't manage more than 33% boost in throughput. COmparisons are tricky to find since Intel stopped doing the top rank Core i5 and Core i7 at the same clock speeds, but a quick look back to Haswell/Devil's Canyon gave up a nice direct comparison between the i5 4690k and the i7 4770k (both have 3.5GHz base and 3.9GHz turbo): https://hexus.net/tech/reviews/cpu/71265-intel-core-i5-4690k-devils-canyon-22nm-haswell/?page=3

What you find in that review is that the i7 has < 35% higher throughput than the i5 in Cinebench, so yes, those Hyperthreads are genuinely worth that little in the real world.

As an interesting aside, one of the strengths of Ryzen is it's relatively good SMT throughput. You can do the same comparison between the Ryzen 3 1300X and Ryzen 5 1500X (https://hexus.net/tech/reviews/cpu/108073-amd-ryzen-3-1300x-ryzen-3-1200/?page=3) and the SMT adds around 45% more throughput. So an 8C/8T Ryzen probably wouldn't beat a similarly clocked 6C/12T Ryzen….
So instead of listening to the criticism of the product lineup fragmentation of features, Intel have decided to double down on their stupidity. In comparison to AMD who try to make features more broadly available across their product lineup.

I'm more interested to see the price difference between the two, taking into account the above point. :)
