AMD has always been known for the mid range and lower range price vs performance leaders. I cant see them coming up with amything to dethrone nvidias top lineup, and even then their drivers are still shit (this is coming from someone which had 2 580RX or whatever the fuck they were, cards int heir kids computers)

Likewise, I have recently had lots of driver issues here, but I held on to my 570 8GB. Worst problem I had was weird screen blanking, sometimes every 3-4 seconds. Required required rebooting to fix. Pretty sure its something with their down/upclocking algos is **cked up. Pos drivers/firmware for otherwise passable cards really. But the younger kids are too young to care.... and older ones.... can buy whatever they like with summer job $$ if my shit dont work well enough for their liking.

Things now stable enough now I can hold out to see what sort of affordable 1440p or low end 4kish offerings AMD and NVIDIA can throw out for the next generation (Navi/RTX+). Who knows, perhaps there will be another 9700 Pro type success.

So Metro Exodus is on gamepass PC now, fucking gorgeous @ 3440 x 1440. I was skeptical about RTX but it does make a pretty decent difference. Never saw the FPS drop below 70 with my new rig.

I'm not sure there will be an AMD equivalent for another year

5700XT, $449, 5700 $379, both come with Gears 5 and PC Pass. Some Ryzen CPUs will, too. The gears game kinda looks like a badass Division?

They're going after 1440p...no real flagship 4k card yet. Might never been one if the Cloud stuff takes off.

No mention of 3950X CPU either.

Lisa Su: 2 surprises at close:

1 more GPU, 50th anniversary 5700XT signed by Lisa Su $499...a bit beefier than the XT, amd issue only

1 more CPU: beyond 12 cores...

confirmed:

3950X, 16 core, 32 thread, 3.5 base, 4.7GHz Boost, 72MB cache, 105W, $749...available in September

What do I actually need 32 threads for

When you're running 32 windows of porn across multiple monitors while playing a video game, chat program, and other shit.

Though to be honest, over a certain core count, even well optimized multithreaded games have a relative cap around 4 cores before gains become miniscule at the same clock speed. They're really for studio work, live render work, manipulating 4K content, encoding/decoding, etc. Not really for games or internet browsing.

Chrome browser and two tabs.

Don't be silly. It's for reencoding high bitrate AVC porn to HEVC (or maybe AV1 in the future) because why is this shit encoded at 20mbit? it's fucking porn-- or maybe she's not pretty enough for 20mbit. (no I don't have a problem)

Hmm thats really what threadripper is for, more pcie lanes + quad channel memory. AM4 lacks both of those so this is purely a halo product. AMD can brag about having 16c on a "desktop" platform while all Intel has is 8c.

Looking like the $349 3700X will be the best price/performance unless you need the 12c for streaming or something.

mkopec · Jun 11, 2019

That depends, it looks like the next gen consoles will be sporting the 8 core AMD chips so maybe games will take advantage of more and more cores? Im sure 8 is enough but I would think 6 would be obsolete in next gen. I would not even touch a 4 core anymore. Unless it was a surfing comp for your grandma or some shit.

a c i d.f l y · Jun 11, 2019

The more games that start to utilize Havoc, DX12, Unreal Engine, etc, etc, since muticore support is baked in...

Fucker · Jun 11, 2019

Looks like MS fixed the scheduler for Ryzen with their 1903 update. People are reporting nice boosts in synthetic benchmarks. My mainboard went TU, so I got a 450 and loaded 1903 and thought the whole experience was smoother...I put that down to better support for Ryzen 2...but it looks like it was 1903.

My box is completely ready. 3600X or 3900X depending on benchmarks.

wilkxus · Jun 12, 2019

Yep, their POS scheduler sucks a lil less now. AND it only took two years to fix. At least it should help lift all Zens as the CCX is here to stay a while.

First 3950x benchmark.

And this is with non-final silicon clocked at 3.3GHz base, 4.3GHz boost.

AMD Myrtle - Geekbench

Benchmark results for an AMD Myrtle with an AMD 100-000000033-01 processor.

browser.geekbench.com

Here is the Intel for refrence..

Intel Core i9-9900K Benchmarks - Geekbench

browser.geekbench.com

Intel-
6209 Single-Core Score
33998 Multi-Core Score

AMD
5868 Single-Core Score
61072 Multi-Core Score

Really close to single core performance, proably will hit it with retail clocks, and doubles the multi core performance but thats to be expected with double the cores.

Is there basically a CCX per 4 cores?

I'm thinking the 2400G is a single CCX and the other half goes to the GPU function. So basically the 2200G and 2400G and their Zen 2 equivalents won't benefit from the improved scheduling.

I don't see benchmark improvement on my 2400G, anyway. (GPU disabled, Vega 56 for graphics).

Big Phoenix · Jun 12, 2019

For 14nm and 12nm processors(1xxx, 2xxx and all G series) it's 4 cores per ccx. For 7nm it's 8c per ccx.

That's true. Though it looks like they will use something similar to the 3700X, it's likely to be clocked much lower. I definitely wouldn't go any lower than 8c now.

Looks like the scheduler fixes require a new Chipset Driver, before any pure performance benefits are seen outside of synthetics benchmarks like 3D Mark.

Perfect timing for me, as the new driver has literally just dropped for my motherboard.

Fucker I also thought things felt "smoother" with 1903, but put it down to wishful thinking. Perhaps there are multiple benefits to be had. Off to do some before and after FPS testing now.

I found the same thing in the few benches I ran. It feels smoother, though.

Yep
4 cores in a compute complex (CCX) still.
Zen 2 has double L3 Cache per CCX though ! (16MB instead of 8MB)

* See Zen 2 Architecture @ Hexus.net
See CCX size @ Anandtech

I'm thinking the 2400G is a single CCX and the other half goes to the GPU function. So basically the 2200G and 2400G and their Zen 2 equivalents won't benefit from the improved scheduling.

Correct, those 4 cores already share the same single L3 cache. Only CPU to GPU communication goes over Infinity Fabric in APUs. Just remember that 2x00G APUs utilize Zen 1 cores. The upcoming 3x00G APUs utilize Zen 1 + cores (same as 2700x). Next years 4x00G APUs should utilize Zen 2 cores. Not known yet if these Zen2 APU will be on its own 4/8 core chiplet with a GPU chiplet or a monolithic Zen2+ GPU die. If next gen APUs have more than 4 cores they will like this patch.

I don't see benchmark improvement on my 2400G, anyway. (GPU disabled, Vega 56 for graphics).

You wont. But anyone with a multiple CCX configuration will see more predictable results with less inter CCX L3 ping pong. It should lift min fps some in games.

Heh, dont get your hopes up, I believe its only 4 cores in a CCX still, just double the L3 cache now on 7nm.
