3800x vs 9900k

[Robert896r1]

A few points on the 9900k that might need updating:

- A 5ghz 9900k gets ~12,800 in timespy. Maybe that's a stock score?
- You can run 5ghz without an AVX offset. Most of us do. You can use OCCT and x264 stress tests to test avx stability
- Your cooler needs to able to handle out 230w/150a *On a 9900k* to be effective for stress loads. However, you'll not see those loads in gaming or normal workload. Doing a ton of rendering being the only exception thus the x264 stress test

I don't get why the 3800x exists. All it appears to be is a 100mhz faster 3700x for a extra £50. Surely the 3700x makes more sense or if you want more then bite the bullet and get a 3900x.

I don't find RAM speed limit a disadvantage on Ryzen.
If it can achieve top performance with 3800 MHz kit and the other system needs 4400, thats another plus for 3800x

Find the cooling requirements for both are unequal. Again, 3800x can achieve its top performance with much smaller cooling.
But to OC 9900k to 5GHz with AVX, you pretty much need water.

And finally the equivalent X470 motherboard for Ryzen would be cheaper. The only added feature of X570, the Pcie4.0 is not available on Z390.

These things add up to a price difference of a tier in GPU, and thats pretty much checkmate in games.

 

[Mr_Sukebe]

I'm a little confused by the comments about pricing.
In the OP, the 3800 system appears to only have 8GB of ram, so there's no wonder that it's cheaper.
Give them the same level of ram, and the CPU cost saving is more than made up for by the additional cost for the motherboard.

 

[Robert896r1]

Also if someone is going through the trouble of tightening b-die on Ryzen, they'd do the same on Intel. Since intel doesn't have fabric scaling tied to mem clock, a good tuned setup for a 9900k would be 16-16-16/4000or4133.

Fought myself with exactly the same argument. But I do hope that once the BIOS's have matured the 3800X does show its worth. Mine does 4.6Ghz+ on 5/8 cores (obviously not when at full load) but never ever can I get it past 70W power draw when others have 140W+.

Pleased as punch with the performance uplift over my 3770K setup, but like you say, there isn't much in the 3700X vs 3800X currently other than epeen at the moment. Though folk paying for binned 9900k's for an extra 100Mhz works out to be more than £50.

Chip manufacturers have cottoned on to the silicon lottery and have started binning chips themselves, they've expanded their own product lines, instead of one CPU line and the consumer plays the lottery in what the receive.

I remember the E2160 intel core2 duo which would overclock insanely for the price point. I think OC'ing other than benching, has seen it's day. Now you just get the chance to squeeze the last few % out of CPU's and GPU's, as Intel, AMD and Nvidia just release them as binned expanding their product stack. And as a business why wouldn't they?

@zx128k have you got Destiny 2 to test by any chance.? I'm still CPU bottlenecked quite a bit even after upgrading my ram to samsung b-die running at 3800cl16.
Game is running at 3440x1440 on R7 3700X stock and GTX 1080ti.

 

[zx128k]

I am destiny 2 as well. I can run 60fps solid @ 4K highest settings with depth of field low and motion blur off (I just don't like motion blur). I am using a 2080.

could you unlock fps and test this area for me please.? it is Sirens Watch landing zone on Titan looking down from the platform. As you can see it drops to 77 on that screenshot but can go down to high sixties or up to low eighties.
I'm gaming at 100fps so drops like that are annoying.
Would love to see how 9900K behaves in that spot...

 

[zx128k]

68-85fps in that area. Highest settings hit the GPU the hardest. Really you need a 2080ti for these settings.

no mate at my resolution my 1080ti is running at 75% in that spot so its clearly cpu that cant push more frames.
if you tested at 4K can you lower resolution scale to offload it to cpu..? thanks

 

[zx128k]

@z10m 1080p is 148 varies between 130-155fps.


This is the latest game build running on stream. There have been lots of changes.

So the price war we wanted is starting, https://www.youtube.com/watch?v=08sLzjWAtPQ

Nothing wrong with what I am getting. https://www.pcinvasion.com/destiny-...-a-sight-for-sore-eyes-in-more-ways-than-one/

1070ti

I promised myself I wouldn’t get a 4K display, but I ended up taking the plunge anyway. I’m glad I did because Destiny 2 is quite a visual treat at 4K.

With the aforementioned specs up top, these were my average FPS rates using different presets:

• Highest – 45-50 FPS
• Medium – 60-70 FPS
• Low – 80+ FPS

Anyway, when I down-scaled to 1080p, these were the results:

• Highest – 130-140 FPS
• Medium – 140-150 FPS
• Low – 150+ FPS

for a 5GHZ AVX clock I needed one of these, the AIO had to go in the bin :

Spoiler

I am very happy with it as well.

omg that is epic in every way possible. My water cooling somehow seems mundane now.

You need a full custom water cooling loop for that build. Most 9900k's don't go above 5.1GHz and 4.9GHz AVX. Sure the top 1% is faster but you will spend £300+ on water cooling and more on fast ram.

The 3800x is faster in every way to the 3700x. It's better binned. With IF 1900 + 3800 fast tight timing, with PBO and auto OC +200MHz. You will be 4.4GHz all cores in games, boosting to 4.574GHz in game as well. The only time it drops in under heavy loads, like benchmarks. The 3800x this way is faster than stock 9900k's and most OC'ed 9900k's as well. It's only the top binned chips, fast RAM and expensive custom water cooling that is faster. Most builds don't spend £500 on the best ram and cooling.

Most of the time my 3800x uses 70-80 watts in games fully overclocked. Hits a maximum of 51c.



The issue hear is that an extreme overclocked 9900k is faster. The elephant in the room i that all 3800x's will hit IF 1800+ with tight RAM timings 3600+. This mean almost all 3800x's will see close to their maximum gains. A stock 9900k is about 10k time spy and a stock 3800x with 3600 RAM that has tightly tuned timings and IF 1800 will hit 11k time spy. At stock this is the scores, https://hexus.net/media/uploaded/2019/8/78005056-1fb3-4a05-9e7a-1b726717d602.png

October 22, 2018 review of 9900k, not 11k in time spy stock. Not 12k @5GHz Then came the security patches in 2019. Free 30% off performance.

Overclocking the Core i9-9900K was not as fruitful. The best bit about this overclock is the 4.7 GHz value: by using our own voltage settings, we reduced power consumption by 41W, almost 25% of the total power, and also reduced temperatures by 24ºC. That's a safe idea. Even 4.8 GHz and 4.9 GHz was reasonable, but the temperatures at 5.0 GHz might not be for everyone. When all cores and threads are loaded, this is one warm chip.

i think you will find that many peeps here will switch between AMD/Intel hardware depending on mood.

Happy to switch in a TR3/3950X but i have a feeling that Google and Amazon are getting the best bins whereas Intel is happy to give the best bins to us in order to prop up their 14nm sales and i only like to buy binned chips atm.

There are only 30-40k of us worldwide that are REALLY into this kinda stuff, Intel/AMD won’t need to provide many chips to keep us happy but if AMD options are all sold out (as per my situation at point of purchase) the. it’s not even and option for me.

spare a thought for the minority of enthusiasts that love the AMD CPU tech but won’t jump in just yet.

It's this that gets me, without massive RAM overclock. Default ram speed for 9900k
Memory Types DDR4-2666 https://www.intel.co.uk/content/www/uk/en/products/processors/core/i9-processors/i9-9900k.html

Review with Memory 16GB (2 x 8GB) Corsair Vengeance Pro RGB 3,466MHz DDR4, just fast enough to pull the 9900k ahead but slow enough to keep the 3800x behind. Here a 9900k hits the speed of a 5GHz all cores 9900k and this is stock. No wonder the 3800x can't keep up.

Take here were a 5.1 GHz 9900k is stock. The 3800x is so much slower.

I wonder if we will see a creeping up of IF frequency and associated memory controller capabilities as the months go on.
Folk keep banging on about the 9900k overclocks but Zen2 has other areas where lots of grunt can be found like IF @1900 ect.

Der8auer was doing some high IF/5ghz zen2 testing recently - might be worth a visit again when the 3950x comes out with (hopefully) two decent chiplets.
