You clearly don't know how complex electronics manufacturing works, putting aside the R&D required for a processor like this manufacturing a highly complex die such as Ryzen 9's with a large number of cores and cache is expensive. The price goes up rapidly as the die size increases the same as you see a big leap in prices from APS-C up to full frame, a few years ago you'd have needed an HEDT platform to go beyond four cores and now you can get 12 cores for under £500 with a consumer motherboard.

Great price. If you do more than just game on your pc and do any productivity or cpu based workload, this is far better than most of Intels lineup!

Highly unlikely it will drop 90% in price in a few years. It might drop to £250-300. The reason flagship CPUs dropped over the past 10 years is due to massive performance improvements.

We are now reaching a performance ceiling

Tbh CPUs haven't improved much, I'm still using a 2500K from 2012 and have no problems maxing any games out. This is why ARM have caught up with Intel as they've been focusing on getting the power consumption and heat down.

That said for editing 4K + you need a modern CPU like this.

The 2500k was probably the best cpu I ever owned, paired with a gigabyte z68 motherboard it sat at 4.4ghz on air.

In 5 years this'll still be well over £100 on cex. 3770K is still £110 and it's over 7 years old. The highest end chips on a given platform always hold their value really well (see 5960x vs 5930k, 2.2x the price for 1.33x cores)

As for why it's more expensive than a laptop, well it's much much much faster than a laptop. Or infinitely better in computing tasks that a laptop simply cannot do at all.

This is better than anything intel has full stop.
As are its stable mates.

Its proving to be pretty hard but people need to wake up to the fact intel is out of the game for now.
Over in server land where they know what they are talking about (not hanging on intels marketing BS) Intel is gone. There CPU's are completely obsolete.
In reality its the same on the desktop, intel have given up and eventually when there marketing BS fades away its going to be an AMD whitewash.
And Ryzen 4xxx is going to make the gap even larger again.

The whole gaming thing makes no sense. We all know gaming is driven by GPU performance yet intel are still making people believe they need a 9900k before that nice new 2070 or 2080! Or splooge and get both and then use all that GPU HP for playing in low detail and low resolution, LOL!
And like, thats all we ever do on our Personal computers.....

Groan.


The only negative I will say about this CPU is unless your doing some seriously heavy lifting its complete overkill.
Never have i seen so many threads sat idle for so long........
Not too salty about this one as I can't see anywhere on the store page that the two games are still included, only the Game Pass. So me paying only £15 (£465) more for two games that are each worth more than that on their own is a good sacrifice for me.

However, if the games are still included in this, or other shops that do offer the games decide to match this price, then this is one hell of a deal.39511483-9hRdX.jpg

Well... imagine you spend let's say 200 million quid to develop a product... you find one and only manufacturer in the world that can actually make it for you... and that manufacturer invested another 500million quid to develop technology to allow manufacture of your product and another 500million quid to build factory... lets say after 5 years of work where you were just pumping money into this new product, paying employees, engineers, etc... you have 2 years to sell your product before it becomes obsolete,

now say that raw materials for your product cost you 2 quid... how much are you going to sell it for?? 3 quid? 5 quid? 100 quid? or basically as much as people are ready to pay for it??

Could be worse, I paid £520 at the end of last month for the same processor. I should take the same advice mentioned in another 3900x thread and not look at these deals....that said I'm extremely pleased with the processor and build so not going to complain.

2500k was a beast I remember mine well. However I'd say unless your playing relatively older games, like pre 2017, you'd benefit nicely from a new processor. Something like a 2600 with 12 threads for new games should be good.
Just doing some random browsing and i saw this on a site that doesnt care about hardware, just does game reviews. But extensively tests hardware against the game:

"but like most games you'll only need a decent midrange processor to max out just about every potential GPU"

Shame the forum cant have an auto reply so that can be posted everytime the key words 'Intel' and 'Game' are detected.
This price is awesome to be fair.. does anyone think this will be sub 400 by february? Long shot but its been falling quite hard of late. TIA

That's true however the offer is also "while stocks last" so Amazon may have run out of stock as they are currently not actively advertising the free games on the 3900x page. If someone buys this, let us know if you get the games too!

Haven't had any problems so far, however I expect I will do shortly as I'm going to be tweaking my memory timings to get the best performance possible and I definitely will get some failed attempts.

I was originally going to go for a kit of 2x16GB G.Skill Trident Z 3200 CL14 ram but it went up in price by almost £60 the day I was going to buy it so I ended up going for a kit of Team Group Xtreem "8pack Edition" 4000mhz CL18 4x 8gb Quad channel.
overclockers.co.uk/tea…tml

I don't plan to run the ram at 4000mhz as that would result in a major performance penalty. Instead I plan to use the Ryzen DRAM Calculator to work out the best timings and manually run it down at 3800mhz CL16. Then overclock the Infinity fabric to 1900mhz and tada, best performance you can get! However this depends on how lucky I got with the quality of my 3900x so it's not certain I'll get 3800, and more likely I'll end up with 3600 CL14.

If you don't plan on doing any tweaking or overclocking, then I would highly recommend a kit of 3600mhz at CL16,16,16,36. The brand doesn't matter that much. as long as it is 3600 at CL16,16,16,36 as that will pretty much ensure you get Samsung B Die chips which work very well with Ryzen.

For example, Here is a great kit of 16gb at 3600 CL16 that will work with no problems out the box with Ryzen.
overclockers.co.uk/tea…tml

The ram will run at 2400mhz as standard so all you need to do is go into the Bios and activate the XMP profile and you'll be flying! (Don't forget to update the bios too as my father forgot to do this and he was having major stability issues untill he updated)

Hope this helps!
How good is this compared to the i9
Omar1980uk28/12/2019 08:57

How good is this compared to the i9


Depends what you want to use it for! 9900K has slightly better single thread performance, for things like gaming. The 3900X would still be good for gaming, but its real benefit over the 9900K is for productivity and multi-threaded workloads (rendering and photo/video editing).

In many cases yet, and frankly AMD are currently superior in many or even most tasks or in terms of what you get for the price, BUT they arent faster at everything.

For the money though frankly its a whitewash. As AMD eliminate the remaining footholds and advantages Intel do have, Intel is going to need to pricecut or make some real advancements. This being said they have the money and manpower to do this, so I dont doubt a riposte is coming but it may take a few years.

This is from someone who just built several AMD builds, I am no Intel fanboy, but I am also not writing them out or off. There ARE still circumstances where they are better BUT for the vast majority of people AMD now offer equivalent or better performance for the cash. Single/low threaded games/low thread count due still slightly favour Intel however due to the higher clock speeds and lower latency inside Intels current ++++++++++ designs and fabrication.

Once AMD have eliminated these areas of weakness, which it made good steps towards with the 3000 series, it is only going to get more severe from Intel until they release a new architecture or process node allowing them to improve thier current one.
But it will come. Intel are a behemoth 10x AMDs size and then some.

Unfortunately Intel are not gone in server land yet either due to contracts and ecosystems already in place, but to say AMD now have a superior offering is an understatement.

Unfortunately gaming is not irrelevant here. Whilst the GPU does most of the work, CPU provides it the work, so if you pair a powerful gpu with a weaker cpu you can end up with bottlenecks, lower minimum framerates etc. This is a reality which has borne out over generations and isnt going to change any time soon.

This being said. A 300 CPU with a 500 GPU will get you an undeniably better experience than 500 CPU and 300 GPU, as all CPUs are now competent and very fast, unlike when Bulldozer based designs from AMD were considerably slower, but the point does still stand that for the absolute best peformance and benchmarks you need as fast a cpu as possible to feed the GPU with as little latency as possible.

nice write up and no fanboyism. I am considering intel when the price comes down on the 9th i7 for faster clock speeds and better gaming experience. But the 3900X is indeed tempting. 10th gen specs leaked today also.
