Great overview both of you, and a special thanks to Mr Kanter for the extra insight(and excitement for the next 4 years in the silicon tech space). Any chance you could get him to find out more on the Infinity Fabric 2's behavioral characteristics/qualities and limitations please? That's the tech that really has me excited, and I'm sure that AMD aren't going to stop at improved audio solutions. Maybe affordable truly scalable multi-die GFX solutions for us gaming nerds? ^__^

Hi Steve so i have a question for you. So i recently got in to overclocking and as i am overclocking my cpu witch happens to be an 8700k. And my temps where really high at 5.0 GHz often in 100s c with prime95 torture test. And in cina bench i was thermal throttling so after about 2 mouths of watching deliding video tutorials. I decided to get the rocket 88 for 1151 and some liquid metal and i used loctite gel control to re seal the IHS. Lets say my experience was not so good as the original glue did not wanna come off and i was having difficulties applying the liquid metal. Having to wipe and reapply i also used acrylic conformal coating for the pcb over the pins. So once i got it all done back in my pc and sure enough ddr4 boot loop. I begin trying to figure out what exactly went wrong taking stick out putting them back. And in doing so discovered that ddr4 slots 2 and 4 are not working correctly. Every time i put a stick in DDR4 slot 2 or 4 the pc gose memory boot loop. DDR4 Slots 1 & 3 are working just fine. So im thinking i May have damaged the memory controller on the cpu die somehow. My question is there something i can maybe do to reverse this or will i have to get another cpu. Any help would be appreciated very much thankyou. Ps im a big fan of you channel. And even though im having the issue with the ddr4. The deliding did work extremely well as i now sit in the lower 70s in prime95 under stress test. my test results are as followed before deliding Base line at stock 34 C at idle 94 c under 100% load in prime95 Cinebench stock speed all cores 84 c. Now overclocked to 5.0 GHz at 1.368V multicore enhancement off ram OC Profile disabled Prime95 100 C under 100% load thermal throttling cinebench all cores 95 C that is my baseline After deliding prime95 stock 55 C under 100% Load Cinebench all cores 51 C overclocked same 5.0 Ghz at 1.368V Prime95 72 C under 100% load cinebench all cores 68 C that is my results from deliding but anyway i just wanted to share that even though my experience was not the best the results almost blow me away

Finally a meaningful video about Navi. This is what makes Gamers Nexus the best.

@@Skewel Me either. It's definitely aimed at mainstream consumers. I think the features are very nice and won't show up in benchmarks since they focus on FPS. For the XT version, personally, I'd wait to pick one up for 350$ or less, not sure I'd pay 400$. Still, it depends on what you are wanting, Navi is overkill for people wanting to play games at 1080p.

In addition to the interesting stuff in this video there is also Radeon Image Sharpening, Contrast Adaptive Sharpening and also Display Stream Compression, all of which will not show up in the benchmarks. And also anti-Lag. So the image will be superior and a benchmark won't show that. So it's a lot to figure out but the features need to be accounted for and not just a FPS benchmark, which are looking like they soundly beat the rtx 2070 anyway. Hope Gamers Nexus does some more deep dives into Navi.

​@@Skewel If you're wanting to buy a brand new Vega 64 or 2060 it's worth going a little extra for the 5700. It's also worth noting that the 5600 series (5600 and 5600 XT) will launch after Polaris and Vega sell out. Also, Navi 20 was running behind schedule, that's why they launched the Radeon VII, to get a presence in the high end market while they work out the kinks in Navi 20. You can expect an announcement for Navi 20 around December, with the 5600 and 5600 XT launching by November. Navi 20 will likely be 3-4 GPU's, 5800, 5800 XT, 5900, and maybe 5900 XT. 5800 will be better than a 2080, 5800 XT will be somewhere in between the 5800 and 2080ti, 5900 will compete with a 2080ti, and a 5900 XT will compete with a 2080ti Super. RDNA is also likely going to age extremely well, which is why I say it'd be worth going for a 5700 instead of Vega 64 or 2060. Hope this helps

Just to say, would love to see more videos of David and architecture discussion (though I understand that the number of videos would be small) xD

This guy explains GPU architecture as naturally and easily as someone explaining the combustion engine. To improve engine power, you can either make the drive shafts in an engine spin faster or increase the displacement (size) of the engine. More bang in each cycle or more cycles with less bang each time. Top layman’s video.

In the first 3 minutes of this video something I thought of was actually brought to light. If Navi is scalable why not couple it with an existing architecture like gcn to make coding for the new architecture to be a smooth transition. Great vid!

PLease something similar for Zen 2/Ryzen 3000 if and when possible.

did i just missed it or does the navi arch have no feature like HBCC?

Hi steve i need your helps pleas. i have ASUS Crosshair Hero 6 motherboard i try to update the Bios last night i download the latest version i rename it than i install it with Ez-updater the system reboat to bios and install it, than once it reboat the Q-code ( LED Debug) keep showing Rondom codes. i try to Flashback the bios i plug the USB dirve in dedicated slot i press Bios botton for 2 seconde it starts blinking 5 time than it stops blinking and the light keep on. can you help pleas.

Is this the CISC-to-RISC version of GPU? Like how the modern x86 break the CISC instruction into RISC instruction in their micro-ops unit. So they have the benefit of keeping the resource low on a resource hungry program and at the same time increase the IPC to a RISC level architecture in expense of having to use an extra energy (Wattage)

Very interesting to think about.

@4:41 nice to see growth

Thanks for the video. That's hitting the nail on the head right there. The way I've come to understand it, and reinforced by this segment. Navi can reach 100% utilization on smaller workloads than GCN (1 or 2 clocks vs 4 clocks), which is why it is technically more efficient running games with only a thread or two. Conversely, this is what makes GCN so much better at Premiere work than Navi, because at 100% utilization it handles this larger workload much better with say 4 or 6 threads. Correct me if I'm wrong of course. Edit: I'm not sure 'threads' is the appropriate term when dealing with gpu so... grain of salt.

What a cool Dude! Excellent! Thank you Sir

Nice with some "no bs" talks. Very good interview.

Where can I see the presentation?

Great video. Based on the explanation of the arch, these cards should perform so much better. Fingers crossed i say

Those dedicated issue units and dedicated scalar units are gonna much a huge difference. Add in the single cycle execution per wave, maybe we got something here.

Unbiased discussion of Navi and Rdna it was great !!! Keep up the great work GN. My 1st post in KZread comments.

For gods sake, give me more of this!

Would be great to listen to his views on the ryzen 4000 series chips ....

More Like that. Its very interesting stuff 👍

3 questions: about the wave thing 1. Is the 64wave the same as on vega? So does that mean a 64wave code isnt faster on the rdna wave? 2. Can you make a whole code in only 32waves without having any drawbacks to code in 64waves? 3. Would a code completely written in 32waves be 4 times faster than on 64waves?

6:38 - I would argue that one core is more closely resembled by one SIMD unit than a CU. If you only have one wavefront (64-wide vector program, now "Wave64"), only one of the four 16-wide SIMD units in a GCN CU will be occupied for 4 cycles per instruction. RDNA changes that, in that a 64-wide wavefront will now occupy one of two 32-wide SIMD units for two cycles per instruction. The overall vector execution capacity of the CU is the same, but the full potential can be exploited with just two instead of four wavefronts. There is also a new execution mode called "Wave32", where a 32-wide wavefront will occupy one of the two 32-wide SIMD units for just one cycle per instruction.

Do these changes negatively impact general compute performance?

Dying to know about the background picture that is bugging the cam. Who is it and what is he holding?
