Gigabyte Confirms Mystery Ryzen 7 5700 And Ryzen 3 5100 CPU Specs
Thanks to the chips showing up on a Gigabyte motherboard's CPU support list—as pointed out by regular leaker 188号, better known as @momomo_us on Twitter—we now have clarification on what these CPUs actually are. The Ryzen 7 5700 and Ryzen 3 5100 are, much like the Ryzen 5 5500 before them, cut-down Cezanne APUs with the GPU removed.
What that means in practice is that memory latency is overall lower. Likewise, folks trying to save every cent are very likely to dip their toes into overclocking, and most Cezanne processors will hit higher DDR4 memory transfer rates than Vermeer CPUs—sometimes as high as 4000 MT/s. Because of the lower latency, having that huge 32MB "GameCache" isn't quite as critical for Cezanne.
There's no question that Zen 3 is an inferior architecture to Zen 4; clearly, these are last-gen CPUs on a last-gen platform. The saving grace is that they are likely to be extremely inexpensive. The Ryzen 5 5500 is available right now for just $99, and that's a six-core, twelve-thread CPU that includes a competent CPU cooler right in the box.
We wouldn't be surprised if, when these CPUs appear at retail (assuming they ever do), the Ryzen 7 5700 shows up at $150 or less, while the Ryzen 3 5100 is likely to be in the neighborhood of $65-$75. Sure, four cores and eight threads isn't great for gaming in 2023, but it'll suffice if that's what your budget can spare. Likewise, there are still Socket AM4 motherboards available in the $75 range.
If those prices end up being realistic, we're talking about board, RAM, and CPU on a still-very-capable architecture and platform for like $200, and that's with 32GB of hot-clocked memory. Throw in a used or hand-me-down graphics card and you could get away with a quite capable system under $500, and that ain't bad.
