The E-cores may be tiny, but offer impressive performance, and when deployed in large-enough numbers, have an enormous impact on the multi-threaded performance. The 8P+16E Core i9-13900K beating the Ryzen 9 7950X; and more importantly, the 6P+8E Core i5-13600K beating the Ryzen 7 7700X, is forcing AMD to reconsider CPU core-counts across its product-stack. The first sign of this is the discovery of a Geekbench submission, where the popular benchmark detects the unreleased Ryzen 7 7800X as a 10-core/20-thread processor.
Given that AMD doesn't have 10-core "Zen 4" CCDs, the 7800X is a dual-CCD chip, like the Ryzen 9 7900X. It has two CCDs with 5 cores, each; and more importantly, 32 MB of L3 cache, each. The engineering sample of this processor is configured with a base frequency of 4.50 GHz, and 5.40 GHz boost. There's no word on availability, but given that the Core i7-13700K crushes the Ryzen 7 7700X in both gaming and multi-threaded performance from the reviews we've seen (expect our review soon); AMD would likely replace the 7700X at its $399 price-point with the new 10-core 7800X, and lower the 7700X to a price-point closer to that of the i5-13600K. There's another equally interesting processor that surfaced on Geekbench—the Ryzen 3 7300X.
The AMD Ryzen 3 7300X is an interesting part, and with it, AMD hopes to eat Intel's lunch in the high-volume Value segment dominated by the 12th Gen Core i3. AMD has made integrated graphics standard with the Ryzen 7000-series, so the 7300X can directly compete against the likes of the i3-12100, i3-12300, etc. This is one segment where Intel lacks the Hybrid architecture or E-cores; and AMD can match it in CPU core-counts.
The Ryzen 3 7300X is a 4-core/8-thread processor with "Zen 4" CPU cores (confirmed to be "Zen 4" based with the 1 MB/core L2 cache size). The processor has a single "Zen 4" CCD, with four cores disabled, but with the L3 cache left untouched at 32 MB. The chip has an impressive 4.50 GHz base frequency, and 5.00 GHz boost. The specs on paper should make the 7300X a formidable rival to the likes of the Core i3-12300, especially given that Intel is expected to rebrand "Alder Lake" into the 13th Gen for the lower end of its product-stack. There's only one fly in the ointment, and that is I/O. The 7300X only supports DDR5 memory, unlike the Core i3-12300, which also supports DDR4, which adds to its cost-effectiveness.
The Ryzen 7 7800X posts a Geekbench multi-threaded performance of 16163 points, which is halfway between those of the 7700X and 7900X due to its core-count being exactly halfway between the two; while the 7300X has a multi-threaded score of 7682 points, which matches the likes of the Ryzen 5 5600X. So you get the multi-threaded performance rivaling a 5600X, with the IPC or single-threaded performance competitive to "Alder Lake."
I personally believe AMD needs to increase core counts across its entire CPU range to better offset Intel.
