Ahhh i went for the i9900k over this 3 weeks ago because of the price difference , now they're the same price-ish.

I’ve always gone intel and I am super nervous about jumping ship. My last build lasted me 7 years. Cost of the X570 mobos are sky high too. I’ll build over the holiday period and see how it goes. The 12c was just too much to resist. I bet the i9900k rig is pretty good too.

Unless you "need" PCI-Express 4, then a higher-tier X470 board is better value than a cheaper X570.

I recommend the ASRock Taichi.

Thanks for the recommendation but I’ve already purchased a Gigabyte Aorus Master x599. I liked the power capacitors and power phase on it. Like I said my last rig lasted (in fact still going strong) so don’t mind the spend as hopefully it will be over 7 more years. Also Gigabyte RMA is UK based. I sent them an email and they replied within the hour- pretty impressive really.

Didn't their 'new socket itis' yank your chains? Did for me. Meanwhile AM4 - well, quite a socket now. Sure Zen 4 might be different but Intel would have had at least a few different sockets by now.

With the price of nvme drives tumbling X570 is a good buy.
I wouldnt worry about dropping intel. 18months ago I had 5 intel rigs. Now all bar 1 (my daughters) are AMD and im so glad i swapped over.

Their new socket- yes certainly. But the cost of the TR4 Mobo and the cost of the new 3960x just took it out of that cost/performance bracket for me. Don’t get me wrong I’d love that new chipset. Just looking for something that’ll see me through the next 7 years.

Because they had serious supply issues with the 12 & 16 core chips which kept prices high, but that seemingly has rently improved.

Just take my advice and stop looking at 3900x threads. Anyway just gun a go look at the price of the 3800x







To see how the price has changed since I bought mine!

Bit the bullet at 520 oops


Same here....oh well, great processor and very pleased with mine.
If you're building a PC for gaming primarily, go for either the 3600 or if you're willing to spend this much money on a CPU, an i9-9900K. And I must emphasise, don't buy the top of the line CPU and pair it with a cheap graphics card if it's for gaming. (For other use cases - video editing, photo editing, this CPU may make sense.)

Yeah pleased so far, but it runs hot when OC'd so I "had" to install water cooling. Well that's what I convinced myself anyway!

I mainly game, but I also do a bit of Premier Pro work as well and so the Intel Quick Sync gives it the edge over Ryzen working with the formats I do, despite the extra cores. If the Ryzen had been this price a few weeks ago mind i think i would have taken the plunge just for the newer architecture.

Enjoy the new build!

Went for the Taichi Ultimate on the Z390 board, loving the 10gb Interface. As it came included I went out and bought a switch and 10gb card for my server and it made it a lot more affordable to get the 10gb connection up and running.
This really should have been priced at £100 more than the 3700x for instance. £200 more for 4 extra cores doesn't translate to you feeling you've invested your money well. What with probably having to get other parts in a new build.
It all adds up fast. And this is a 'bargain' price from it's former pricing too.
Almost double the price of the 3700x for the extra chiplet (extra heat?), 4 extra cores and 200 extra mhz..
While the 3700x also has a power draw of just 65w to save on the lecky too lol.
Might get one down the line if they end up much cheaper on ebay when the next gen come out.
New consoles (8 cores), Your new console killer will get laughed at if you don't have one of these. Wish ide remembered in time.

I understand what you are saying but it all depends on your useage. If you want a cpu for gaming, I agree a 3700x with a x470 mobo and use the difference to get as good a gpu is the way forward. However I need as much RAM and cpu horsepower as possible and an 8c would get bogged down quicker. Would love the 16c and 24c offerings but they are just way too pricey presently. The 3900x also clocks higher and boosts higher so the chances are I’ll be able to keep the platform longer. That’s my logic. The 3900x is a premium product and therefore priced accordingly. Intel does the same.

Yeah, no doubt m8, was just gutted a bit that I couldn't fit it into my budget because the price difference is off, my parts added up to a massive amount even while getting many bargains along the way. Waiting for next year for a GPU upgrade.

I feel your pain. My last upgrade I bought an i5 and I wish I bought the i7. I so regretted that and I had to live with that for the 7 years I had the machine. I still love it to bits, but just getting long in the tooth. I just think if I had the i7 the system would have had another year or so left in it. I use my machine for home and work use and some days it is on for 12+ hours. We all have to bite the bullet and make a purchase. Of course it will be cheaper in a few months- it always is and there is also something newer and better around the corner. Without spending £500+ on a TR4 mobo and the cheapest TR4 compatible CPU is £900 even if you can get your hands on one, I still think this is a pretty "cheap" CPU for cost/performance depending on your work type.
I've just sold my 10yr old rig which has lasted me sometime and unbelievable that I managed to get nearly £90 for my old motherboard on ebay. I had a x58 asus p6t deluxe and i7 920 which has ran really well for 10yrs and now finally updated to a x570 taichi and waiting on my 3700x to arrive. I did buy a 2700x but returned. Figure I only update every now and again no big deal to spend more on motherboard. Still cant believe or even understand why my x58 was in such high demand 10 yrs later.

Good look with the build. Let us know how it goes. I think it was smart to exchange for the 3700x and definitely best band for buck cpu presently. I have a Asus P8Z77-V LX. Bought for £86 and my curiosity got the better of me. On eBay- £20-£70. Potentially 7 years' usage for £16. Bet I don't get that sort of return on my present purchase.

Intel have been doing this for the last decade with the i3<i5<i7 and everyone seemed more than happy forking out ludicrous amounts of money? I find it funny for years people have been saying 'pay a bit more and go Intel unless you're on a really tight budget' (myself included) as you did get slightly better performance, but now AMD have Blitzkrieged Intel with Ryzen (especially Gen 3) releasing CPU's on par with Intel for a fraction of the price people still find reason to complain.

The 3800x is priced slightly higher than the 3700x as it's binned higher which involves a fair amount of extra testing to ensure it's stable at the higher base/turbo clocks. The 3900X has another 4C/8T, an extra chiplet, in the same package, that in itself is a marvel of engineering, but on top of this also has a higher turbo clock speed. The in house binning process on these chips is insane the fail rate is much worse as the tolerances are so tight.

For reference I've been (was) an Intel fanboy probably since the 90's but the last few years they have just stagnated, they got comfortable and made huge cuts across their R&D worldwide and this is the result, they can't keep up with AMD. Up until a few years ago if you wanted to game you got an i5 and if you wanted to do a bit more you'd put maybe another £100+ into an i7, you didn't even get any extra cores that's just to have a chip with Hyperthreading enabled which gives a reasonable performance boost in multi threaded workloads. It was just a given, an unwritten rule, that if you wanted to stream/video edit etc. you'd be looking at a decent chip for £1k+ that's just how it was.

Only going back 2 years you can see how greedy Intel got before their downfall: pcworld.com/art…tml

This would explain why Intel have had to slash their prices by up to 50% and they're still struggling: uk.pcmag.com/int…ent

Here are a few benchmark comparisons to Intels more recent chips just for fun, obviously don't take these as gospel but I think the results are pretty telling:

cpu.userbenchmark.com/Com…041

cpu.userbenchmark.com/Com…043

cpu.userbenchmark.com/Com…044

cpu.userbenchmark.com/Com…057

cpu.userbenchmark.com/Com…057

So anyway yeah right now is the best it's been for years value wise, great time to be building and/or upgrading. If you're just gaming pick up a 3600 or 3600x and put the savings towards a better graphics card as that's where you'll see much better gains/return. If you need something like the 3900x for heavy workloads (like myself) the performance improvements are insane, I might hold out for the 3950x tbh but horses for courses. Peace

I did the same thing with going i5 instead of i7 lol so I get what a dilemma that was and instead of buying the i7 years later I moved to ddr4 and Ryzen because I've been wanting to use one of these Ryzen chips for ages.
Yeah the price probably makes sense, I may get the 3900x next year and sell the 3700x, there is no real reason to, it's handling encoding video edits, multi tasking, games brilliantly. Well happy.
To be fair the i5 was a great chip too, never really felt much performance loss even considering I remux video files a lot and play CPU intensive games.

Great post! Thanks for all the info, I already knew most of it tbh lol. But cool anyway. Useful for anyone reading the thread.
So many possibilities these days, next years GPUs... hope the nutty pricing structure of Nvidia cards drops. Or see what the AMD cards offer, need the video encoding side of things to play nice with all editing software, so hence the Nvidia bias.
Happy PC building to all of you who bought parts for Xmas!! Looking forward to building mine over the next few days.
