Performance is better than I expected, especially for 300w and while not verified externally, it looks like AMD is finally competetive with the top end. If they can get the required share of TSMC volume, then Nvidia may feel a bit of pain since Samsung seems unable to meet the demand.
- Tuna-Fish 6y agoNote that the 6900xt benchmark was running in "rage mode", and therefore was not inside 300W. Then again, the card they are comparing to is ~380W, so there is some room to play with while still being more power-efficient than the competition.
- filmor 6y ago"Rage" mode, what a nice name choice coming from ex-ATi :)
- 013a 6y agoAlso important to note that it had Smart Memory Access on, which requires a Ryzen CPU (and furthermore, did they say specifically a Ryzen 5xxx CPU?)
- kllrnohj 6y agoThey said Ryzen 5xxx and x570 chipset.
- noir_lord 6y ago500 series, that would cover B550.
- rasz 6y agoWhich is Intel level of dubious fake market segmentation considering those are no longer Chipsets, but rather southbridges sitting away from main PCIE lanes and memory buses.
- kllrnohj 6y agoA possible plausible explanation is that AMD's SAM is "just" that they fixed the BAR size limits so the entire vram can be mapped at once, instead of the still weirdly common & low 256MB limit. If so, that would actually involve the chipset (even if it's just the supporting BIOS & microcode) and not just the CPU.
- rasz 6y agoBut there is no chipset. PCIE controller is on CPU die.
- kllrnohj 6y agoThe software that runs the PCIE controller isn't on the CPU, though. And at least at launch only the 500 series chipsets support the Ryzen 5000 CPUs. Maybe this will come to the 400 series chipsets later that get Ryzen 5000 support, or maybe this is something that was cut to squeeze in Ryzen 5000 support for the 400 series chipsets.
- rasz 6y agoWhere do you suppose its running then? Its pure market segmentation with AMD dictating what runs where totally incompatible: https://www.itworldcanada.com/article/amd-zen-3-processors-will-be-incompatible-with-400-series-and-older-motherboards/430513 https://www.itworldcanada.com/article/amd-zen-3-processors-w... erm, we means totally compatible!!1: https://www.tomshardware.com/news/amd-reverses-course-will-enable-zen-3-support-on-b450-and-x470-motherboards https://www.tomshardware.com/news/amd-reverses-course-will-e... "chipset" nowadays is just a pcie device providing legacy ports (USB 2.0, additional USB 3, SATA, HDA audio controller, PCIe bridge, I2C, SPI, LPC, bunch of GPIOs).
- zlynx 6y agoI wonder if Smart Memory is even using PCIe 4? Remember AMD uses the PCIe lanes for interconnect between two EPYC CPUs. It's supposedly very similar to PCIe but a bit higher speed. Smart Memory could then be as efficient as cross-CPU EPYC memory access. Which is pretty good.
- floatboth 6y agoSmart Memory Access is just marketing speak for resizable BARs (https://docs.microsoft.com/en-us/windows-hardware/drivers/display/resizable-bar-support https://docs.microsoft.com/en-us/windows-hardware/drivers/di...)
- freeflight 6y agoAt this point SAM seems to be Ryzen 5xxx "exclusive". Makes me wonder if that's related to the improved L3 cache access of Zen 3?
- jsheard 6y agoThe performance numbers shown were cherry picked though, and conspicuously didn't include anything with raytracing enabled. Leaked 3DMark raytracing benchmarks showed Big Navi lagging far behind Ampere so I wonder how that's going to bear out in real games.
- throwaway2048 6y agoVery few games have implemented raytracing
- mcraiha 6y agoBut since both PS5 and Xbox Series X support ray tracing, there will be many upcoming PC games that support it too. You want a future proof GPU when you spend over 500 dollars to it.
- leetcrew 6y agoimo "future proofing" doesn't really make from a price/perf perspective, especially for something so easily replaced as a desktop GPU. by the time the cool new feature goes mainstream, that high end GPU you bought probably needs to run everything on medium anyway. I expect the RTX 2000 series will age very poorly. a better approach is to aim for the price/perf sweetspot for a target resolution and upgrade often. I bought a 1080 TI more because I could than because it made sense.
- doublepg23 6y agoAren't both of those going to be using the same AMD ray tracing tech?
- oulu2006 6y agoThat's what I was thinking, seems a little odd that ray tracing can be significantly behind when both those consoles use AMD tech to implement their ray tracing capabilities.
- nodonut 6y agoA low price and energy draw with ultra 4k gaming, meets the wants/needs for >90% of hobbyists. Assuming no issues with future testing/drivers, the 6000 line is forcing nvidia into a more niche market. Namely, Ml, ray tracing, and "flex" buyers. I wouldn't be that worried if I were nvidia-- catering to the whales is good business, but I think we're looking at amd winning the lion share of the market
- redisman 6y agoAMDs 3080 competitor is $50 less and 3070 competitor $70 more. The flagship is cheaper. In the end, most PC gamers balk at >$200-300 GPUs. These are all niche cards so far.
