    yeah man, imma spend whole ass console prices on a first gen platform high end CPU, great idea.

    im sure all the people that got a 1900x are really happy with how AMD fucked them over on upgradability.

    Trying some PBO settings on a 7800x3D, 90 level 2 (90c cap, -20 all core offset) is actually slightly slower than 70 level 2 (70c cap, -20 all core offset) in CPU benchmarks. Using an AK620 but with a very relaxed (quiet) fan curve. It was just as good or slightly better in single core or multicore tests.

    All while drawing 20 watts, or 62.85 watts max during the test on an air cooler. Even in Cinebench testing it doesn’t hit 100W. I swear, these chips are magic. I probably didn’t need the AK620, but it was on sale along with the CPU/board and it performs as good as a D15 and is quiet. Plus it was super easy to mount compared to my old spring screw 212 evo.

    If you are looking to upgrade and see a good CPU/board bundle, grab one. The performance and efficiency while being so fast is remarkable.

    The 7800x3D is a very interesting chip (and the best for gaming, by a notable amount): when I set my system up with an AK620 the default fan curve in BIOS had the CPU fans going at 1800RPM. But with negligible impact on temps, as these chips are designed to run hotter for clock speed. I put the fan curve to like 30% and tested a few games like far cry 6…same high FPS, no throttling, same behavior. At 1800RPM, the game was at like 50-60C. At 900RPM, the game was at 50-60C. Initially I thought “whoa, I somehow screwed up mounting this cooler even with 2 screws and a simple mount kit”, but it’s intended behavior for these CPUs.

    So if you grab one and you are used to intel chips, be mindful of fan curves: default fan curves in BIOS are for CPUs that have much different fan behaviors! And the 7800x3D doesn’t even draw much power, under 100W and outperforming a 14700K that can draw 300W…my GPU doesn’t even draw 300W in most cases!

    My mind was blown when I saw a 7800x3D for over $100 off on black friday despite being a literal top tier part. you’d expect ryzen/intel chips from 2 years ago to have discounts like that, not the literal best gaming CPU at the moment. It’s nice to see value for these components, even when they are at the top of the stack. given am5 boards are cheaper now (b650s are good value) and DDR5 has dropped in price and 6000/cl30 kits are cheaper now, it’s a great time to upgrade.

    LoL for a second i thought AMD had a change of mind and actually priced their GPUs correctly, a 7900XT for 433 would be quite a good deal and at 650 without black friday sales.

      And a better CPU for gaming. And let’s be real if you’re getting an X3D processor, you’re probably gaming.

Using an AK620 but with a very relaxed (quiet) fan curve. It was just as good or slightly better in single core or multicore tests. From reading people have also done -30 or more (there are options up to level 5, or -50), but -20 has been 100% stable so i’m happy with it.

    All while drawing 22 watts minimum, or 62.85 watts max during the test on an air cooler. Even in Cinebench testing it doesn’t hit 100W. I swear, these chips are magic. I probably didn’t need the AK620, but it was on sale along with the CPU/board and it performs as good as a D15 and is quiet. Plus it was super easy to mount compared to my old spring screw 212 evo.

    If you are looking to upgrade and see a good CPU/board bundle, grab one. The performance and efficiency while being so fast is remarkable. Now I see why people were raving about this CPU so much. Video benchmarks are one thing, but seeing it in action with various games is another.

    7900X3D is such a weird chip with its only 6 cores CCD expanded cache…

    Worse than cheaper 7800X3D at gaming.

    Worse than pricier 7950X at productivity.

    What’s the niche?

        definitely plays a part, just thought it was interesting as i have been monitoring prices, that the price of a full build really hasn’t changed much despite a 4090 for example going up 400$, everything else has gone down in response

      That’s not what’s going on. GPU isn’t influencing the other prices.

      CPU pricing is very competitive because Intel basically always keeps their prices + inflation, so when Zen 3 was priced higher, 12th gen was priced lower, when Zen 4 still priced higher, 13th gen was still priced lower. AMD tries to move pricing up and Intel keeps anchoring it back down, and then it ends up being them in a price war with sales. Even when Bulldozer was a disaster Intel didn’t break change their pricing, this pricing scheme goes back over a decade.

      GPU pricing is ridiculous because Nvidia loves it’s profit margins and sets them high, and AMD simply joins in, slightly lower but usually with worth performance and certainly worse features, so Nvidia and customers don’t care.

      Then you have memory and storage prices tanking because DDR5 is now mature and there has been an glut, too much NAND produced when demand pulled back, leading to very good prices as manufacturers take losses.

        Yeah the reality is that people are going to buy NV pretty much no matter what these days. Their lead at this point is like, 80%+ of the market…AMD is thus not really in competition with NV; they’re more in competition with Intel, if anything. With the rumors lately that AMD is going to release a single midrange card next Gen and that is all, it’s kind of hard to blame NV at this point…when the “competition” doesn’t even try anymore, you just charge whatever the market will bare. I fully expect the 50 series, especially the ~5070s and up, to be even more expensive than the 40 series is for this reason, and guess what? People will still buy them so…🤷‍♂️

        AMD can undercut the hell out of NV, but it just results in Nvidia shrugging, dropping like 10% higher to where AMDs prices are, and gamers thank AMD then buy the NV card.

        lol…its not that deep, the price of a asus strix 4080 is the same price of the MSRP on a 4090 rn…its just simple supply and demand, GPU prices have a large impact on what the average consumer can afford…anyways its a good time to buy everything other than a gpu right now.

      It was $370 end of last week at both Canada Computers and for a short window on Amazon. Sorry you missed it. Hopefully tomorrow it comes down.

        It did not come down.on the Friday. If I am lucky Monday for cyber sales. But crazy it went on sale for $370 the week before black Friday. Seems almost to be done on purpose.

          That would be an insta buy right now, just hoping to see some deals this weekend.

          Most prices on Ebay are marked up to $649 so they can pretend to offer a 20% discount, when in reality it’s something like $20 off.

          I’m refreshing ozbargain and staticice constantly now lol

            Why not go AM5? You can buy 7800x3d + tomahawk b650 for $820 in Australia atm(sale). Add some ram for 150 and you’ll be good. Yes it’ll cost double but you’d be buying into a platform that’ll be supported for another 2 generations.

              I’m looking to replace the CPU only, I don’t have the budget for more than this

              I already run a higher end b550 motherboard and B die RAM.
