News out of E3 to start the day with, as AMD gave out a lot more details on more exciting hardware coming with the third-generation Ryzen 9 and the Radeon RX 5700.
Let's start with the specifications of their new GPU, the 7nm Radeon RX 5700 which will come in three different models. This is the GPU that will be using their brand new "ground-breaking" RDNA "gaming" architecture and they will be the first to support PCIe 4.0.
- Radeon RX 5700 XT 50th Anniversary Edition
- 40 compute units, 2,560 stream processors, up to 10.14 TFLOPS, 8GB GDDR6, 1,680MHz base clock + 1,830MHz "game clock" and up to 1,980MHz boost. Price around $499.
- Radeon RX 5700 XT
- 40 compute units, 2,560 stream processors, up to 9.75 TFLOPS, 8GB GDDR6, 1,605MHz base clock + 1,755MHz "game clock" and up to 1,905MHz boost. Priced around $449.
- Radeon RX 5700
- 36 compute units, 2,304 stream processors, up to 7.95 TFLOPS, 8GB GDDR6, 1,465MHz base clock + 1,625MHz "game clock" and up to 1,725MHz boost. Price around $379.
All of which are expected to be available on July 7th.
To go along with that AMD also announced FidelityFX, an open-source developer toolkit that will be up in "the coming weeks" on GPUOpen. AMD say this will make it easier for game developer to make high-quality post-processing effects while balancing performance and looks. This will include "Contrast-Adaptive Sharpening (CAS)" to give detail to low-contrast areas while minimizing artifacts and Unity will be integrating it.
AMD also revealed their latest 3rd generation Ryzen 9 and it sounds like quite the monster with a ridiculous 16 cores:
- Ryzen 9 3950X
- 16/32 cores and threads, 105W TDP, 4.7GHz boost and 3.5GHz base. Price around $749 and it's launching in September.
That's in addition to the previously announced Zen 2 Ryzen 3 models that will be launching next month on July 7th.
You can find those details and more here.
Considering the pricing level and the performance they offer there, it's quite likely my next machine will have an AMD CPU. This is the first time I am truly considering doing it since my early days of computing! Probably not the Ryzen 9 3950X though, more likely the reasonably priced Ryzen 9 3900X which is still a beast.
Quoting: mrdeathjrNavi is more GCN+ (rdna seems is only a trademark) and tdp seems higher,
I think real change comes with arcturus in 2020
And that's a advantage for Linux users as it means that AMDGPU DRM won't require huge changes in order to work with the newer hardware (hopefully).
I'll definitely upgrade to a Ryzen 2 CPU this year (my i5 3470k is getting old...), but I'm not sure if I'll go for a 5700 (maybe a Vega, if their prices are reduced)

Quoting: EgonautQuoting: chancho_zombieaaand Zen2 got spectre/meltdown hardware mitigations which doesn't turn your cpu into a celeron if you are compiling or doing something else other than gaming.
AMD CPUs don't need meltdown mitigrations and by that won't have any.
I think they are vulnerable to the less virulent version of spectre, spectre v2 and not meltdown, you are right.
Quoting: minidouYep, seems like Navi will be a great generation for AMD. Probably gonna make the switch.
How long does it usually take for the open source driver to handle newly released graphic cards ?
phoronix is making the guess that the code will be in place in September/August, in mainline, so you can boot a distro and be done, but you could probably get development unofficial code sooner.

GCN must be die for future (good for compute but dont enough in gaming), Arcturus maybe can give better tdp and another improvements
However yes is a big change and needs time, amd devs must be stay working now for when stay ready in 2020
Respect your i5 3470k, if you wait until now maybe must wait until next year because appears ddr5 (higher frecuencies) and in your case needs change memory
And maybe amd have better chipsets with better fabrication node 7nm ?, aka better temperatures (passive cooling) and tdp
^_^

i dont know. they promised gaming for low price, but the prices are kinda the same compared with the 2060 and 2070
also nvidia will release a newer version of the 20 series, which should be cheaper
even with 7nm they suck a lot of power and have a high TDP
they also say it is for 1440 and 4K gaming, but they only have 8GB VRAM.
i wait for real benchmarks from independent testers
Quoting: mrdeathjrGCN must be die for future (good for compute but dont enough in gaming), Arcturus maybe can give better tdp and another improvementsNo Arch is made from scratch. So, in the end each new arch is most of the time an iteration of the previous with major improvements. Anyway, what matters for any end user is the performance/price relation (or just performance for the rich people out there), so it's pointless to wait for "the next" if the current gives you the performance jump you need (My two cents).

To be fair, newer memory technologies requires a couple of years to settle and they normally doesn't give a real performance jump until latest iterations. So, as I don't have a very recent CPU, there is no point in waiting any longer for me.

I'll go for a X470 or B450 chipset, so I'll get passive cooling.

8GiB is plenty. I've only got 4GiB, and while it is sometimes borderline, it's still fine for 1440p.

for now. but what about games in 2 years?
a 2070 with 8GB for assassins creed in 4K is on its edge
also it would be a selling point. nvidia still has ray tracing and DLSS
navi benchmarks and prices didnt blow my mind and its not like i can say, that my next card will be an AMD again
Quoting: mylkanavi benchmarks and prices didnt blow my mind and its not like i can say, that my next card will be an AMD again
If you meant for the leaked benchs, those showed that it was slightly better than a 2070. And as the 2070/80 GPU have 8GB of VRAM, there isn't much to choose from both sides in the end (or we have to accept that in two years you will get the same problem on both sides -- still, I disagree with this). By the way, if RT is the selling point, forget about 4K gaming.
Anyway, if you want to game at 4k, you should go for whatever gives you the best performance, so 2080 Ti may be the only real option for now.
