5800X3D vs Alder Lake, Raptor Lake, Zen 4 - Telegrams for Guests

Hi Tom and Max. Id like first to thx Max for making great XOC content, since very few ppl does it. Id like to know what was your favorite cpu or gpu to do some XOC on, and which cpu surprised you the most in the last 4-5 years. Personally my favorites gpu to bench are kepler and Tahiti (im sure Tom can speak on this 1), they both had amazing scaling with voltage on COLD but even at ambient temp. Second question is kind of a follow-up to Bretsummers question. What is your opinion on the recent gpu trend where every gpu is pushed nearly to the maximum out of the box and XOC sku's from aib's are nearly all gone. Now for the most part it seem to just be decent pcb design and custom heatsink with a gaming sticker on it.

Hola max-tom how does testing 0.1% lows versus 1.0% lows differ in importance? Does the end user feel 0.1% lows? Lastly how do you avoid measuring frame drops in a game due to assist being loading in. hitching while the game is loading and starting is not due to the cpu or am i mistaken...

Hey Max, nice to see you back on here, in previous years you tested some of Intel's and AMDs CPUs in WoW under liquid nitrogen overclocks and found the Ryzens don't tend to fare well because of the difficulty maintaining Infinity Fabric clocks and the high memory latency. Had you been able to overclock the 5800X3D, do you think that its large L3 cache would have made it fare a lot better? Also, have you run any of the HWBot benchmarks on the X3D yet, any thoughts in that regard?

Hello Tom & Max. I own a few AMD rigs though AM5 is in my future, I'm thinking of standing pat with my R7-2700x and mate it to my ROG/Crosshair x370 with 32GB RAM and using to strictly to be in an emulation box (aka retropie). I plan on using my X470 ROG/Crosshair to a new Ryzen7 5800 or 5800X3D. I will buy a new or newer GPU too. The expense of the new platform being an early adopter with DDR5 cost is ridiculous. Seems to me basically anyone's new platform will have issues besides cost. I mean look at the issues that Intel had with some games in Windows 11. So good Idea to wait on AM5 because I am not a pro-gamer?

Hello Tom and Max! Greetings from Turin (pun intended)! My question is one I’ve been asking myself for a while now: When will the revival of Intel’s Costa Rica fabs make a difference in the battle against TSMC? This news dropped a few years ago now (how time has flown!) and it was said at the time that this move would take a while to bear fruit for Intel. Do you know any new information about this project and how Intel plans to accelerate their node development to counter TSMC? Contrary to popular opinion I think that their own fabs will be to their own advantage once again because under competent leadership, which Patrick Gelsinger is proving to be, they will be able to tightly integrate their products to a level Apple and TSMC are only doing right now, and if they keep up the level of innovation on the fab and architecture side equally, then that would be a dangerous prospect for their competitors. Sorry for the little rant but I haven’t heard much from Intel’s fab progress lately and I’m getting a bit anxious on how that is progressing! Take care and keep on rocking!!

Hi Tom and Max. Have any of you played arround with FSR on older card like Vega og Gtx 10 series? I am curious what this technology could do for these older cards.

Hello Tom and Max, hope you guys are doing well. Just have a simple question: Do you have think traditional overclocking is dead? I mean you can still do it, and tweak certain things...but not like back in early Nehalem/Sandy Bridge or Core 2 days. It seems to me that unless you have exotic cooling, your overclocking will generally be limited and restricted to only a few things to get only a few more percentage points of performance out of it.

I have a 3700x on a msi x570 meg ace I primarily game (1440p, 2080ti) but I do multitask (watch YouTube, monitor discord and have multiple game launchers updating in the background while I game) and from time to time even light content creation. Its nothing the 3700x can't handle for now so any upgrade to a 5000x will be a decent lift. My question is as I'm looking to maximise my platforms longevity (measured in years) against the demands of future game/ software. how should I balance the faster cores of a 5900x/5950x against the vcache of the 3800x3d? Should I go up core count or up vcache? For reference one retailer here has the 85000x3d for £409, 5900x £359 with the 5950x being £499. I think there's a fair few in a similar situation so thank you both for your thoughts.

Overclocking is cool, but what about under-volting! When evaluating multi core high performance chips I would be very interested to hear who has the best silicon for meeting the stock performance numbers but at the lowest voltage. Currently I have a x5900 and would be interested in seeing if I can keep my current boost clocks but drop the voltage down to reduce heat load on my system.

There has been a lot of discussion of alder lake vs zen 3/3+ at high wattages, I'm actually more interested in the efficiency curve. Ive seen testing that below 35-45 watts, zen 3 is better, I wonder if you'd tested in these lower power scenarios?

Hi, Tom and Max. Which Zen 4 models do you expect we'll see get 3D stacked cache variants? It seems like a double-edged sword in that lower tier models won't gain much from it, where as higher tier risk thermal problems. Do you expect them to release one for the highest end model this time? What other uses do you expect AMD will find have for 3D stacking, aside from cache in future architectures?

Considering the competition we’ve had in the consumer CPU space these past couple of years and next gen console being equipped with 8 core 16 thread processors establishing a new baseline for development, how do you see CPUs being pushed by developers now that we’re getting a lot of cores and ridiculous IPC gains?
