AMD Ryzen™ 9 9900X 12-Core, 24-Thread Unlocked Desktop Processor

Computer now starts up in about twenty seconds. (All AMD) Really fast. Sorry, I'm not a gamer so can't speak to gaming with it. But I run an AI from within the computer rather than using the cloud, using LM Studio, and it answers within a couple seconds every time, often nearly instantly, whereas it took half a minute or so with a very fast AM4 processor and it's slower memory, with the same video card. Installation was easy as expected and it runs cooler than my previous processor on the previous AM4 motherboard. The AM5 socket this uses and this processor support very fast memory frequencies up to 6000, which is where much of the quickness comes from. Its running Windows 11 with no problems.

The AMD Ryzen 9 9900X 12-Core, 24-Thread CPU is a beast, handling my workloads and games smoothly, just like my old Intel Core i9-13900K setup. The 4.4 GHz base and 5.6 GHz boost keep everything snappy, and it’s great for multitasking. Feels very similar in performance, though I expected a bit more of a leap. Still, it’s a reliable choice for a high-end build

Had the 7900x and bought this 9900x to save power7900x idle like 11kwh a day9900x idle like 6 kwh a dayThat being said, 9900x uses slightly more power if you were to be using it all the timeSo for example, 9900x it uses like 10 more watts under load than 7900x for why I was using itOf course this is also I also Ihad my 7900 X under volted to the 120 W tdp and even still underload 7900x would use it less power under load most of the timeBut idle is what my computer does most of the time and it’s significantly less power usage under idleFor example, 7900 X was 234w idle9900 X can go down to 170 wAnd then it seemed like overtime. It actually learned how to use even less power at idle, the 9900xI’m happy

Good cpu, I'm using it with my Gigabyte 5070 OC Windforce graphics card that I also got through Amazon.

I know this one isn't specifically meant for gaming but works well for gaming. Powerful processor and stays cool with proper liquid cooling.

Jesus Christ, upgraded from a 10900k to this BEAST!!!!!! THE 9900X WOW!!!! this cpu is so much more powerful than Yahweh, and any system ive had before,Who needs religion when you can have AI baby, im so impressed with this CPUThanks, Jeff Bezos for the deal on this CPU, my elite masters i love them all

WOW, was debating some other chips and looking into overclocking and also making sure I dont bottle neck anything this was what I landed on. I paired it with a 7900xt and don't get any issues in bottle necking and the AMD on AMD boosts my OC ability. I will say that AMD is pretty Hot out the gates BUT they under tune all chips to work with a stock air cooler. THAT being said I originally paired this with a 420mm AIO, unfortunately when i did my build i did not like how the 420mm fit in my ceres 500 and went with a 360mm instead and stock THAT is plenty! at idiel I get around 37c and playing games like Fort, Marvel Rivals, delta force and Ready or Not I MAX out at like 60c running 2k or 4k and getting 120fps (2k) or 90-100fps (4k) (NOTE: i cap all frames at 120 unless i can push 144) ... after running it with Ryzen utility and doing a auto OC I get a boost in about 30-50 frames and NO temp difference for a budget CPU for gaming this one hits the mark perfectly!

Overall this is a great processor to have for multi-purpose use. A single CCD 8-core processor is a little bit better for gaming, but the difference is often negligible. I have minor complaints in that the mismatched CCDs seem to affect user modifications. For example, setting a negative voltage in PBO will result in instability if you set it per core or per CCD and properly tune it due to the second CCD running significantly lower voltages and driving the averages down. You'll have to manually match the second CCD to the first even though it can take much lower. Voltage seems to be applied to the whole CPU on a weakest link basis and sometimes it just doesn't go up fast enough because of this.The mismatched CCD thing is strange. The second CCD uses less power and runs at lower speeds but also drives overall power usage down a bit. I'm not sure how well it's managed. In a way it's almost like economy cores except they're full fledged "performance" cores, just running lower with less voltage and power. If the SoC smartly routes high end things like games towards the first core running at full speed, it should get pretty excellent results. But then again, I have yet to see any single core go more than one or two over 50% in total usage (counting SMT) in any game and most are around 30% or so, so I'm not sure the lesser speed of the second CCD really has any effect on gaming anyway.I do wish modern Ryzens didn't run so hot. Starting with Zen 3 they all are designed to just go ahead and max out pretty high thermally. AMD has raised their maximum limits pretty high compared to previous generations which seems great, but there is sometimes some very heavy thermal cycling. It's like slamming your car into a gear that puts it in the yellow line every single time you go up a hill even if it's not that steep. That won't tear it up on its own, but it isn't good for its longevity either. Not that Intel is doing any better in this regard... I do feel like the chiplet architecture of the Ryzens is still superior in a lot of ways though, not the least of which being that it's completely OS agnostic and can manage fine points far faster and more directly than the motherboard or the OS. I hear these are still cooler than the Zen 4 processors however. I can only say that it absolutely runs hotter even in idle compared to my previous Zen 3.Still, all this stuff aside, AMD's Ryzen processors are a pretty good for quite a lot of multi-purpose uses, including both gaming and applications. Intel might get slightly higher benchmarks, but these will run cooler and more efficiently while actual user experience will feel about the same. You also have far more control over over/underclocking or things like voltage (though the mismatched CCD issue I mentioned does make me feel that is decreased slightly, it's still better than the controls you get with Intel.) All in all I'm getting really good performance and results from this CPU.
