Ryzen 7000 has some IMPORTANT Secrets!

AMD announced the Ryzen 7000 series with Zen 4 architecture but there are some important secrets they didn't talk about before release and availability. Let's talk about what details about memory compatibility, power consumption, IGP performance and more means for the Ryzen 9 7950X, Ryzen 9 7900X, Ryzen 7 7700X and Ryzen 5 7600X.

Small correction! FCLK is 1733MHz by default. We didn't catch Rober Hallock's confirmation on this. :)

[johndoh]

Dude, you compared DDR4 16GB to DDR5 32GB. Doesn't seem quite right to me.

[LucidStrike]

Early AM4 motherboards often had just 16MB BIOS chips, limiting their capacity for SIMULTANEOUS support of so many CPUs. Newer ones had 32MB, so they didn't have that issue. AM5 standardizes 32MB as MINIMUM. So, yes, the early boards are setup to support a good number of future CPUs.

[yousuff]

Please don't degrade this channel with clickbait titles like "secrets". The content is good enough and there were no secrets told in this video.

[Zicrixdoesart]

Feels a little dishonest to compare "125 vs 55" for motherboard. Where is there a $55 motherboard? Would you trust it? How many people are actually running that. Most for am4 were $130ish and that felt more than fair

[bigherb]

Comparing pricing at the end of the life cycle of AM4 with a brand new socket and ram generation at launch. Seems pretty fair to me 😌👌

[Kizzster]

How is $125 eye watering? Also I'm seeing DDR5 32gb at $160, 16gb at $99 (5200mhz mind but you can overclock DDR5 more than DDR4). I expect prices of DDR5 to go down more within a few months as there will actually be competition and demand for it because currently it's just Intel that supports it and there's barely any performance gain right now.

[Nicc]

i think my 5950x will be with me for a long time. I heard alot of good things for am5 but I will wait until bugs are fixed on launch. So much to look forward to for end of year and next year, exciting times :)

[iliasiosifidis]

Thx for the summary, a small objection on pricing, b550 mobos are usualy 100-120 for a decent part, and you compared ddr4 16 gb with ddr5 32 gb

[johndoh]

DUDE, AMD will release LOW PRICE OPTIONS. Jesus CHRIST!

Can Youtubers figure out launch and release patterns??? AMD WILL release a 7700 and a 7600. You know why I know? Robert SAID they would release their typical 65W and 105W TDP parts. Did they launch their low cost parts for Zen 3? NO. Just stop it, please.

Enough with the attack dog crap at LAUNCH. It's like saying NVIDIA won't come out with a 4070. SURE they will. Just because they haven't officially talked about it and are going to launch a 4090 to start with doesn't mean there won't be other products.

[LordWanFu]

Okay, there's some seriously *_dumb shit_* said in this video that amounts to piss-poor journalism and/or click-baiting. If you are reporting on technology, you shouldn't be getting basic stuff wrong:

1) The L2 cache was increased instead of the L3 cache because the L2 cache is much closer to the CPU cores than L3 cache *and* it runs at much higher frequencies than the L3 cache. As such, it allowed for the performance increase that they were looking for. It would take many times more L3 cache to give the same performance boost their L2 cache increase accomplished -- and would probably consume more power as well, because the increased signal length (and therefore the need for repeaters) leads to more resistance and capacitance. And last I checked, L3 cache does not take up more die space than an equivalent amount of L2 cache. If anything, L2 cache can take up more space than an equivalent amount of L3 cache because it can use a more advanced set of FETs/NFETs in the SRAM that take up more die space.

2) How exactly has the cost of entry increased? There's some seriously dubious math being used here. For starters, the 7600X costs as much as the 5600X when it debuted, so technically it costs less in light of inflation (and increased materials cost). And why are you comparing the cost of entry for B550/5600X/DDR4-3600 *_ONE YEAR AFTER ITS RELEASE_* to the cost of B650/7600X/DDR5-6000 *_three weeks before release?_* Holy shit! You mean new stuff costs more than old stuff!! You are a financial genius!! That's it. From now on I will only buy old stuff!!
And as an aside, what B550 motherboard are you referencing that was $55 and isn't a complete pile of garbage? $55 puts you in the Biostar or bottom tier ASRock territory -- which you should *not* be encouraging anyone to use, especially if they think they're going to keep it for 4yrs and upgrade to a higher wattage CPU at some point.

3) Remember that B550 chipset motherboards are PCI-E 3.0 only -- save for the 4x PCI-E 4.0 lanes coming from your Zen3 CPU dedicated to M.2 storage. B650 provides at least 4x PCI-E 5.0 lanes for an M.2 device and everything else from the CPU and the Chipset are PCI-E 4.0 lanes. Zen4 CPUs also offer 28x PCI-E 5.0 lanes vs Zen3 CPUs offering 24x PCI-E 4.0 lanes. (Now imagine what motherboard manufacturers can do with PLX/PEX chips to bifurcate those PCI-E 5.0 lanes.) B550 and B650 aren't anywhere near each other in terms of being "budget" offerings -- especially when you consider the fact that nobody will actually *need* 16x PCI-E 5.0 lanes for a GPU any time soon, whereas B550 released with 16x PCI-E 3.0 lanes at a time when AMD had RDNA2 cards on the market using PCI-E 4.0. Again, it is dumb to complain that stuff that comes out in 3 weeks costs more than 2yr old stuff, particularly when the new low-end raises the bar by such a significant amount.

4) Yes, AMD doesn't include an HSF any longer. For some people, I suppose that's a bummer. However, this is essentially offset by AMD ensuring that existing AM4 HSFs can be used on AM5 motherboards. AMD didn't include an HSF on anything but the 5600X, IIRC, for the Zen3 generation, so...? And if you don't already have an AM4 cooler, then I guess you have to buy something like a Vetroo V5 for $25-$35. Probably still better for the environment than the stock cooler ending up in someone's wastebin.

5) The increased cost of DDR5 over DDR4 has nothing to do with AMD's new processors. Unless you are suggesting that they should have clung to DDR4 for another 2 years while DDR5 prices stabilize to around current DDR4 prices? If anything, now that AMD and Intel are both using DDR5, the speeds will go up, the latencies will go down, and so will the cost. DDR4 memory cost more back in 2020 than it does now. Again, you're stating the obvious: new stuff costs more than stuff that's been out for 2yrs.

6) B650E lists PCI-E 5.0 x16 for the GPU as "highly suggested" whereas B650 lists PCI-E 5.0 x16 for the GPU as "optional". This simply allows motherboard manufacturers more market segmentation. They can decide whether they want to spend additional money/time/engineering for PCI-E 5.0 signaling or use cheaper/less stringent PCI-E 4.0 signaling while only using a single chipset. Remember that the *_core_* difference between B650 and B670 motherboards is that B650 uses one chip and X670 uses two of the same chip.

7) "Zen 3 was already a challenge to cool..." Huh? What are you basing this on? Since when? Also, it's quite a leap to assume that the increased thickness of the IHS on Zen4 CPUs is an attempt to help with cooling -- especially when AMD themselves have mentioned that the increased thickness of the IHS is what allows for compatibility with AM4 heatsinks. The increased thickness allows them to maintain the same Z-height for Zen4 CPUs on the new AM5/LGA socket as the old AM4/PGA socket. More thermal mass on an IHS can be a good or bad thing depending upon a whole host or thermodynamic parameters. Also, if you look at a delidded 5950X, you will see the same approximate spacing/placement of the I/O die and the two CCX chiplets as you see on a 7950X. The major difference is the I/O die is now 6nm TSMC instead of 14nm Global Foundries -- which should be a huge savings in terms of energy consumption and/or heat output, even with the handful of included RDNA2 CUs. Finally, remember that AMD's formula for TDP is nothing like Intel's and that each individual processor actually uses a different formula.

Perhaps you should actually watch (and take notes) on AMD's presentation before making a video?

[madd]

thanks for letting us know about the RAM. I will make sure to buy two sticks of 32gb.

[billkillernic]

2:33 you got it wrong 1x2rank doesnt mean 2 sticks of ram. it means 1 stick of ram that has chip on both sides (dual RANK) so for two sticks of ram (dual CHANNEL) the speed is 3600 Mt/s the thing that is not clarified though in said presentation is if they mean per channel (which would mean 7200 MT/s for dual channel) but given the previous history with AMD and ram I wouldnt be so hopeful.

[StaySicEver]

Definitely great their platform is supported for years to come though. I'll wait for 3D-cache chip and I hope 6000MHz C30 kits will be priced better by then. But yeah obviously latest new tech will cost more than existing one that's been out for years, not to mention discounts too. Excited for reviews.

[diablo]

You're comparing an entry level DDR 4 16GB kit to a high end DDR5 32GB kit...

[johndoh]

When AMD said 2025, I took that to mean through Zen 6 for AM5. That's the only guarantee AMD is giving. I'm sticking with that. The + simply means driver support, AGESA updates if needed, that kind of thing.

The reason for Zen 6 is because Zen 5 is a change in architecture, Zen 6 is a refresh and Zen 7 is another new architecture. AMD might need to move to a new platform for Zen 7.

So, for sure AM5 is good through Zen 6 and as far as support for the platform even if they move to AM6 that will continue on. My guess is that would continue at least for another 3 - 4 years.


L2. There's less L2 than L3. AMD has gone onto TSMC N5. CERTAINLY there was space ON-DIE for double L2. But that's only part of the issue. Going off-die means slower speeds. L3 can be stacked because it's the slowest cache. There's no guarantee that any other cache COULD be stacked. L2 runs faster, L1 runs fastest.



Why the fuck does every Yutuber have to go to SALE prices as a comparison for Zen 4. Be happy AMD discounted the 8 and 16 core parts and left the 6 and 12 core parts the same, and this makes SENSE. For AMD, they need to make a certain amount of money off a core chiplet regardless of 2 cores disabled or not.

It's fair pricing. AMD does NOT have to say, "well, we have a 50% discount right now so that's how we have to price NEW parts" NO. AMD has NEVER done that. AMD has ALWAYS discounted products as time goes on. Stop comparing an MSRP to SALE prices. If you don't want to pay the price for new technology, buy older tech or wait. AMD puts products on sale once they have built up product. So please stop attacking AMD for not basing NEW pricing on SALE prices. It's stupid to think a company needs to do this. They could NEVER put products on sale then. The expectation would be after about 6 - 8 generations that the products are free, if the company put products on sale. I'd rather AMD does what they do because I know I can use patience and get a discounted price on excellent technology in about 8 - 12 months.

[devontoner]

honestly the heatsink thing is big news to me, after my emergency computer build I put together when my 3930k died, it was a godsend to be able to buy a $49 open box mobo (asrock b450 pro4m) and using the boxed heat sink with my 3600x, I built a "new computer" with some reused components (storage case psu) for $400 with a trip to microcenter. I needed that machine on a 1 day turnaround and have been very impressed. An aftermarket hsf would have added at least $25 onto the final bill

[c-dub]

"Anything above DDR5 3600 is considered overclocking WOW"
Anything above DDR4 2133 was also considered overclocking. How is this news?

[The_Opinion_of_Matt]

Great video! Lots of things I missed.

[bjn]

2:40 Alder Lake runs 4 DIMMs of DDR5 at 3600 by default as well. Though you can usually manage 4400, occasionally 4800 with 4x setups. AMD seems to be setting a conservative expectation to match.
