Kaby Lake Vs Coffee Compare Review Processor Price Trends Bang Buck

Intel finds itself in an odd position in 2017. Historically, it'south held the whip hand over AMD, but with the release of its Ryzen fries this year, AMD has been making a comeback, its chips delivering more brute forcefulness power than Intel's Kaby Lake CPUs but at far cheaper prices.

Enter Intel's Coffee Lake processors – Intel's eighth generation of CPU – which accept more cores than before and college clock speeds besides.

To discover out what Intel's new chips are really capable of, we put the high-terminate Core i7-8700K through our regular desktop media benchmarks, running on Windows 10 64-bit with 8GB of DDR4-2400 RAM.

Read on to find out if Intel's latest offerings are adept enough to topple Ryzen and reclaim the CPU crown…

Intel Coffee Lake review: Dissimilar models and features

At that place are half-dozen Coffee Lake processors to cull from at the moment: two Cadre i7 models, two Cadre i5 chips plus 2 depression-stop Cadre i3s. All the new CPUs are desktop PC parts, with no laptop versions announced only withal.

Coffee Lake is very similar to the chip giant'due south Kaby Lake processors released terminal twelvemonth. They utilize the same cadre design, and they're besides 14nm chips then no movement at that place. The days of ever-shrinking manufacturing processes seem to be well and truly over.

There are differences between the two ranges, though, with the start being the number of cores. The new Cadre i7 chips now accept half dozen cores, instead of iv, with Intel's Hyper-Threading technology allowing them to deal with twelve simultaneous processes. The Coffee Lake Core i5 chips have six cores simply don't benefit from Hyper-Threading, while the Core i3 models have gone from a core count of two to iv.

That's not all, though. Intel's Coffee Lake chips besides run at college clock speeds than their predecessors. The Cadre i7-8700K runs at a stock speed of 3.7GHz and has a maximum Turbo Heave speed of 4.7GHz, which is an improvement over the four.5GHz of final year'due south model. Yous tin push button it even higher if yous want to considering the scrap is unlocked.

1 word of warning, though: Coffee Lake won't be a inexpensive upgrade. As the new CPUs accept higher power requirements, you can't simply replace the Kaby Lake chip in your current motherboard; y'all'll need a new one equipped with one of Intel'south latest 300-serial chipsets.

Intel Coffee Lake review: Benchmarking

So, how quick is Coffee Lake? In a discussion: fast. Really, really fast. For the first test run, we left our review Cadre i7-8700K at its stock speeds and saw scores of 163 for prototype editing, 202 for video editing and 226 for multitasking for an overall score of 208.

PCs based on the previous Core i7-7700K have typically scored around 180 so that's a large pace up. Information technology's not plenty to unseat AMD, though. Ryzen seven 1700 desktops tend to score around 240 overall at stock speed; with a high-end Ryzen seven 1800X CPU, we'd wait to see an overall score of 270 or more.

How about overclocking? Well, that's a little more interesting. A new feature in the 300-series chipset allows you lot to prepare the maximum Turbo Heave ratio for each core individually so you lot can run every core at the absolute fastest speed it can stably back up. To keep things simple, nosotros didn't spend too much time tweaking it and prepare all cores to the same frequency instead. However, we were still impressed with its performance.

Our test CPU remained stable at speeds up to v.1GHz using a stock Intel air cooler. Thermal throttling rapidly kicked in, though, meaning I saw nearly no real improvement in performance: the overall benchmark score merely rose a few marks to 212. To make the nearly of the chip'south overclocking capabilities, it looks similar you'll have to resort to a pricey liquid cooling system.

Intel Coffee Lake: Graphics

Like the main CPU core, the UHD 630 graphics processor in the new Coffee Lake fries is essentially identical to the i in the previous generation. There's native support for 4K HDR video and slightly higher clock speeds, but those are the just new features.

So yes, information technology is the virtually powerful integrated GPU Intel has withal produced, but you lot notwithstanding tin can't use information technology to play high-end 3D games – at least non without dumbing the detail and resolution downwards significantly. To get Metro Last Light: Redux to a playable level, we had to drop down to 720p and disable motility mistiness and anti-aliasing. Even then information technology reached only a sluggish 36fps.

Intel Coffee Lake: Prices

Intel'south Java Lake range covers a whole spread of cost points, starting at £115 for the quad-core 3.6GHz Core i3-8100, rise to £355 for the Core i7-8700K we tested for this review.

AMD's Ryzen range, though, still offers more blindside-per-cadet and you'll typically get more cores to the pound than with Intel. The Ryzen 7 1700, for instance, has viii cores and handles sixteen threads and costs a mere £265. It's officially clocked at iii.7GHz, only all Ryzen processors are unlocked so you can push it higher.

Then at that place'south the Ryzen 5 1600X, which offers half-dozen cores and can handle 12 threads at 3.6GHz. At £217, it'south cheaper than the Core i5, which tin can just handle half-dozen threads. The Ryzen 3 1200 has four cores and can cope with viii threads, while the quad-core Intel Core i3 is stuck on four. It'due south as well cheaper than the Intel at £95.

Intel Java Lake: Verdict

Intel's new Java Lake chips are certainly more powerful than their predecessors, thanks to the extra cores and college clock speeds. Still, AMD's Ryzen chips still deliver more than for your money and, although they don't have integrated graphics like the Intel chips, that disadvantage is offset by the fact that with the new Intel fries yous'll need to replace your motherboard anyway.

That doesn't mean the Coffee Lake is a useless upgrade. Non at all. There'due south enough power here to punch through whatsoever job, and while the graphics won't print hardcore gamers, for other purposes it's ample and allows y'all to build a arrangement that's both simple and quiet.

At the moment, Coffee Lake is expensive compared with equivalent AMD Ryzen CPUs, but look those prices to fall once the initial launch menstruation is over. That will make information technology a far more tempting purchase overall.
