AMD Ryzen 9 7900

[Minus Infinity]

Since the 7900 is brand new, it costs more at the moment than 7900X. Might as well get the X and use it in ECO mode for the same wattage and performance as nonX.

Exactly, just run the 7900X in 105W mode for a better balance of performance and power. 65W is too agressive IMO. Shame this review didn't try to run the 7900 in that preset 105W mode as the PBO Max and 5.3GHz OC were barely any better than the stock 7900X for power usage.

I have not bought a Gigabyte board in Years but i might have to try one when they get a little cheaper.

The Gigabyte B650 Aorus Elite AX is priced at about $220 at Microcenter as well as at Newegg. OK, it's a little expensive but not entirely so when compared to some other boards that I looked at when I was building my AMD 7700X system. According to this review over at Tech4Gamers, it's getting a favorable review. The only negatives as they put it is that it doesn't have a 4X PCIe slot and no debug LEDs. It does have a decent VRM setup and sufficient cooling, so that's good along with a whole lot of USB ports. For a $220 motherboard, that's really a slam dunk if you ask me and features what most people need on a motherboard while keeping a decent feature set and a decent build quality while keeping the price from reaching into the stratosphere.

7900 also comes with a cooler.

And ALL it needs is that CPU cooler...no need for expensive and sometimes 'problematic' water cooling.

Hard pass for now. Considering that there is already talk about next gen CPU sometime later in the year. I'll just wait... for a while.

Don't hold your breath. Zen 5 is next year. The stuff coming later this year is APUs.

I've got a 7900 for a Graphic Design machine (picked one up around release date). Here's the highlights and pitfalls:

- Long boot times are true, but not horrendous. You get used to it.
- Excellent efficiency. I've seen very similar figures to the TPU tests (rarely going over 75W, 88W spikes, 55W average, regularly in the 40's)
- Pretty good at gaming, but other Zen 4 chips can best it for sure.
- Very strong application perf and perf per watt (why I bought it, helped along by a Gamer's Nexus review too). It crushes the design tasks I've given it.
- I've found the chip to run a little hot at idle, but the temps under load are pretty good (generally in the 50's and 60's with a 360mm CLC. Though, a more demanding game could push that up).

So, it's great, and I don't regret buying it at all, but a 7900X with Eco Mode 105W, or an upcoming 7800X3D will probably be the better option for anyone reading this.

But if you see a great deal on the 7900 a few months from now (especially if you need it for work), go for it!

I haven't seen any mentions of Microsoft Pluton Security Processor in Ryzen 6000 & 7000 cpu's as well as Qualcomm CPU's. It is actually a shame they are NO BUY for me. I could go on for for hours about self-determination, privacy and private key self-custody and storage, but looks like no on cares. NO ONE gets copies of my strong passwords and private keys. Last thing, enjoy your top-level enforcement of DRM, DMCA, Govt. access of GPG, SSH, passwords etc. for the false sense of security using SecureBoot and BitLocker. You've already lost the keys to the kingdom.

AMD's SPP didn't make all that happen. It happens regardless, on every device. Privacy is gone.

When I was at Microcenter buying parts for my AMD 7700X build, the sales rep steered me far away from ASUS motherboards. I even suggested that I was entertaining the idea of going with an ASUS motherboard because like others, I thought ASUS was the best brand one could buy. I could tell he was trying very hard to convince me not to buy one. At one point during the conversation, he told me that they were having a lot of returned ASUS motherboards in both the AMD and the Intel camp. It was like he was telling me to avoid them like the plague.

Users on Reddit seem to also be having lots of problems with ASUS motherboards.

I went with a Gigabyte board instead and have had no issues at all.

Microcenter near me only ever has the worst Asus boards stocked.

Not anymore, at least not on my system with the current BIOS, boot times are 5< seconds.

I was surprised to still see that, as i do not get that issue with my b650 r5 7600 i just built less than a week ago. Maybe is MB manufacture specific?

@W1zzard my boot is less than 20sec from power on button... Is that the long boot time you referring to or way more?

Check my recent ryzen reviews, conclusion, i timed how long it takes, don’t remember the exact number

Yes, mine too. A lot also had that damn Intel NIC on them which I wouldn't touch with a barge pole.

Check out the latest Hardware Unboxed video. The Asrock boot times are crazy good.

Interesting benchmarks. As for the in-browser Jetstream 2 benchmark, this may favor different browsers and versions. I had a low score on my 7700X like 200k points using Firefox, whereas running the test on Edge I managed 309k points. Not sure what browser was used here.


It would be interesting to know what virtualization test was done, for exmaple through virtual box - is this creating a particular VM, OS or doing what? It'd be interesting to know as I've just moved from Intel to AMD and I do use virtualization quite a bit. Thanks!

In a World where you do a Google Search and then get emails in your Inbox on it. A security chip in a processor is not that important.

lol I practice Self-Custody of Private Keys and Passwords and it ABSOLUTELY matters. I believe in Self-Determination and will refuse government & corporate control of my Full ID in device. You may carry on with your stance and enjoy your forced compliance and payments.

It is interesting to note that to fully enable AM5 memory training on some motherboards, you have to enable Memory Context Restore in TWO places. My Asus X670E ProArt wouldn't speed up the boot process until I made both changes in BIOS. YMMV, but more here if you're interested:

"Intel 13700K is faster and cheaper"
No. It's not. Neither faster, nor cheaper, not even efficient.
Oh, you were again, only talking gaming.

?

It's faster in all the rendering tests, the software & game development tests, the web browser tests, some of the machine learning tests, all the science & research tests, most of the tests in the MS Office & productivity page, all the server & workstation tests, all the media encoding tests, and the gaming tests in aggregate.

At the time of the review it was indeed cheaper as well. ($392 vs $429 according to historical data on PCPartPicker)
