Used i7-8700K CPU 6c/12t LGA 1151 £235 24mo warranty @ CEX

Posted 14th Aug 2018
Seems a cracking price for a 8700k from CEX. Comes with 24 months warranty too which is brilliant in my opinion. To be perfectly honest as a buyer of many intel processors, ive never seen or heard of a single intel processor in the last 15? years thats died from reasons unknown. In every case where ive read a processor has died, its down to user error such as too much voltage, or physical damage when attempting to delid.

I also believe if you did happen to have an issue after 24 months of buying this processor, that Intel will be very likely to help you out if you contact them and can prove youve not caused the damage.

Brand new price for this cpu is £320, so almost £100 saving on new for a processor that is more than likely going to be next to perfect condition (not been released that long), seems a good deal in my honest opinion. Also bear in mind this cpu came out in Q4 2017, so its not even 9 months old yet! RRP when this was released was £360 too.

Specs:

Number of Cores - 6-core
Processor Number - i7-8700K
Compatible Processor Socket - LGA1151 Socket
Clock Speed - 3.7 GHz
Max Turbo Speed - 4.7 GHz
Type / Form Factor - Intel Core i7 8700K (8th Gen)
Cache Memory Details - 12 MB
Processor Qty - 1
Type - Core i7
Number of Threads - 12 threads

I think the average user, and yes even those doing video editing etc will struggle to see the benefits of buying one of those large core count ryzen cpus over a 12 thread 8700k mate. Plus this will overclock far higher than any ryzen, so much so that 5ghz is the new baseline for this cpu.

cpu.userbenchmark.com/Com…958

The 8700k comes out on top in most aspects plus this is as 3.7ghz on both processors. Given that the ryzen quits at 4ghz IIRC, the difference when you put that 8700k to 5ghz will be even higher.

After a certain period you don't get a 100% refund but one based on the current price.
Good Price have to agree with the OP on Intel processors, been building computers for last 20 years, never had an Intel process fail even when overclocked (pentium 75mhz overclocked to 120mhz and stayed stable) ...shame I cannot say the same for AMD processors

8700K is at usually equal or better than a 2700x on a great deal of common productivity applications the average home user might actually use, for example winrar or handbrake. I use handbrake a lot and Ryzen is only mediocre on it encoding HEVC, partly due to Intel's AVX extension advantages. In gaming the 8700k still leads, albeit a smaller margin than ever.

AMD are starting to sway me slightly because their gaming performance has improved along with the stability of the platform. Intel has enjoyed more consistent performance across all apps but it is gradually improving with Ryzen. The biggest desktop win for AMD is their commitment to the AM4 socket.

I feel AMD are just a half step behind at this point for your average home user but the gap has closed since the first gen Ryzen parts. Intel are still scrabbling around trying to fix their next generation manufacturing process (it is now 2 years late) and this is what will hand AMD the edge they need for performance desktop in 2019.

2019 will finally be AMD's year, it will be the first time they have a clear lead in most performance segments since 2005 when Zen 2 launches, most likely in spring. No answer is expected from Intel until at least 6 months later in all probability. Been a long time.

This is well worth the price, I've bought tons of PC stuff from CEX in the past and if there's ever been an issue I've taken it in and they've refunded me without fuss, sometimes they might test the hardware first but in my experience even if they can't exactly find anything wrong with it, they still refund anyway.

I still find it funny how you can buy something like an Apple product direct from Apple and only get a one year..... warranty, when you can buy an A grade Apple device from CEX that basically looks and feels new for a fraction of the cost and get a two year warranty...

For gaming primarily not so much. Give it another 12-15 months and pick up a next generation 8 core. That should be a worthwhile upgrade overall and better for when games become more multithreaded.

Nobody was going to make games that use more than 4 cores when virtually nobody had more than a 4 core processor for the better part of 10 years. Within a couple years now everybody will end up with at least 6 or more cores. Gradual evolution will happen.
Thanks for the feedback brothers!
Hope to one day see you on the battlefield of pochinki or the halls of Hereford on siege one day
CEX often lack the technical knowledge and equipment to properly test IT kit. Did you know you can remove the metal integrated heat spreader (IHS) from the processor? That's the silver bit on the top, with the processor identification markings on.

This is a process common for overclockers because the themal interface material (TIM) that Intel use between the chip itself and the IHS is relatively poor. So you de-lid the processor using something like a Delid Die Mate 2, clean off the old TIM, add a better conductor (such as Thermal Grizzly's Conductonaut for the bleeding edge, Kryonaut for the conventional) and then reseal the IHS onto the chip.

Overclockers would generally buy the K-model chips as they are unlocked.

I am curious to know if CEX actually checked these chips are ACTUALLY i7-8700K's, or if they're i7-8700K IHS's sealed onto lesser chips. Will 8th gen i7 IHS's fit onto the 8th gen Pentiums or i3's, and would CEX notice? Something to consider before giving them £235 and finding out for yourself.

1000ⁿⁿ00% no way. Keep the 6700k. No games will play more cores. 8700k is useless IMO. The 6700k is better for gaming.
Had 2 CPU's from Cex in the past. Both had issues with crashing randomly, Cex cant really test CPU's so its a risk you take.

High end CPU's like this are usually overclocked to hell to a point they might be faulty under normal use.

Well since they need to test the processor and put each one in the correct motherboard all setup, you'd assume they will take extra 5 seconds to open cpuz.

Had this discussion on another thread recently. I don't think they test CPUs, but anything you buy from them online can be taken back to the store for a refund. I've had to do that a couple of times and they don't ask questions

I’ve always had a full refund - never had a reduction and I’ve had to return a lot of stuff (not as a percentage). Occasionally it will come back as a voucher not the credit card payment and I’m not sure what determines that.

To be fair all I'd suggest doing is when you receive the cpu just do a 12hr torture test and then if your gonna overclock do it again. If it passes both of these I'd say your good to go

Yes, I returned a 13-month old R9 Fury to them and didn’t get a deduction though it should have been about £20 less at the current price. I think they say it but don’t seem to adhere to the policy and as they’re useless at testing, returns are surprisingly easy for things like that and almost makes the warranty better than other places.

Are you sure about that? If your processor survives a 24 /48 hour Prime 95 stress test, it's 100% stable. Those are operating conditions that will never be approached in the whole life of the system.

As pointed out already, this isn't true.

Here's some reviews on the very topic.

techpowerup.com/rev…tml

Have a look, outside of Video Rendering, the Intel 8700k is ahead of all the Ryzen offerings *before* overclocking.

Maybe a better way to put it is the Ryzen is mostly for video rendering, and if you do video rendering, fine, you know what you are doing and should buy accordingly.

As for 'buying the best bang for your buck' i5 8400 and the Ryzen 1600 are both excellent choices in terms of value to dollar.

The 8400 does better with games and the 'average user' doesn't have to do anything with it to get the best results, while the 1600 gives you good performance and some headroom to play around with overclocking for the 'average user' who may want to explore the hardware overclocking side of things.

Both of these can be picked up for around 150-160 quid.

I'm sure yes. Just because a cpu passes prime95 doesn't mean it's 100% stable and won't get random bsod. Don't know where you get that info from to be honest.
Rocking a 3770k which does everything I need and waiting for Zen 2 and the next Intel 8 core mainstream to release to decide what to upgrade too, it's amazing that a 3770k can run any game out without a hicup once overclocked.

Is that what you learned on Intel fan forums? Lol. I've got experience diagnosing incredibly elusive hardware faults, it's much more complicated than CPU instability if you get random BSOD's even if the BIOS code cites a CPU fault.
If you've got a history of Intel chips cooperating with you then by all means keep buying their products. You do you.
