Quote:However, Intel does have competing models for the Ryzen 5 5600X. Our results show that AMD's Zen 3 microarchitecture simply outclasses Intel's Comet Lake chips at every price point they compete in, sealing AMD's dominance in desktop PCs.
As we can see in our charts above, AMD's advantage of a denser 7nm process node and more refined architecture pays big dividends. The Ryzen 5 5600X is faster than Intel's less-expensive Core i5-10600K across the board, setting a new bar for single-threaded and multi-threaded performance in the mid-range.
Looking across the full spate of Intel chips, the Ryzen 5 5600X beats all of the Intel processors in single-threaded performance - but that's with the 5600X at stock settings. Meanwhile, even overclocking Intel's priciest mainstream silicon, the Core i9-10900K, doesn't help against the Ryzen 5 5600X at stock settings. Overclocking AMD's chip only increases its lead.
...
We can expect Intel to respond with lower pricing as Zen 3 availability improves, particularly over the holiday season. Until then, if you're looking for a lower-priced alternative to the Ryzen 5 5600X, we stick with our previous recommendation of the Ryzen 5 3600 (and even the 3600X if you catch it at a good price). We simply can't recommend any competing Comet Lake processor at current pricing.
Zen 3 has completely disrupted Intel's desktop PC chips at every price point it competes in, and we're excited to see what the future Ryzen 3 and APUs have in store. Not to mention next-gen Threadripper. Meanwhile, the Ryzen 5 5600X takes the throne as the no-compromise gaming chip for the mid-range.

Quote:AMD Ryzen 3000 "Matisse" processors based on the "Zen 2" microarchitecture, as well as older AMD processors based on "Zen+" and "Zen" microarchitectures, do not support the company's Smart Access Memory (SAM) feature being introduced with Radeon RX 6000 series graphics cards. SAM is essentially a branding of the Resizable Base-Address Register (Resizable-BAR) feature developed by the PCI-SIG; which enables a processor to see a graphics card's entire video memory as a single addressable block, rather than through 256-megabyte apertures. Apparently the PCI-Express root complex of Ryzen 5000 "Vermeer" processors introduce an instruction called full-rate _pdep_u32/64, which is required for resizable-BAR to work.
It gets more interesting—Intel processors have been supporting this feature since the company's 4th Gen Core "Haswell," which introduced it with its 20-lane PCI-Express gen 3.0 root-complex. This means that every Intel processor dating back to 2014 can technically support Resizable-BAR, and it's just a matter of motherboard vendors releasing UEFI firmware updates for their products (i.e. Intel 8-series chipsets and later). AMD extensively advertises SAM as adding a 1-2% performance boost to Radeon RX 6800 series graphics cards. Since this is a PCI-SIG feature, NVIDIA plans to add support for it on some of its GPUs, too. Meanwhile, in addition to AMD 500-series chipsets, even certain Intel 400-series chipset motherboards started receiving Resizable BAR support through firmware updates.
