A slightly thrilling unannounced AMD cellular Ryzen processor has simply surfaced. The Ryzen 9 5900HX (through Tum_Apisak) might be a part of a brand new breed of Zen 3 cellular chips that will help overclocking, just like Intel’s unlocked HK-series elements.
The Ryzen 9 5900HX, which confirmed up in an unreleased Asus ROG Zephyrus GX551QS laptop computer, comes geared up with eight cores, 16 threads, and as much as 16MB of L3 cache. Present Ryzen 4000 (codenamed Renoir) processors have a most L3 cache of 8MB, which implies that the Ryzen 9 5900HX ought to belong to the subsequent technology of APUs referred to as Cezanne. Moreover, the Ryzen 9 5900HX carries the Household 25 Mannequin 80 identifier, the identical as Cezanne.
It is not confirmed but, however Cezanne may wield AMD’s newest Zen 3 microarchitecture that has been confirmed to ship a substantial IPC (instruction per cycle) enchancment compared to over Zen 2. The Ryzen 7 5800U has already gave us a sneak peek of what Zen 3 may deliver to the desk for ultra-thin gadgets so it is thrilling to see what the microarchitecture can do in a much less confined thermal setting.
AMD Ryzen 9 5900HX Specs
| Processor | Cores / Threads | Base / Enhance Clocks (GHz) | L3 Cache (MB) | TDP (W) |
|---|---|---|---|---|
| Ryzen 9 5900HX* | 8 / 16 | 3.3 / 4.6 | 16 | ? |
| Ryzen 9 4900H | 8 / 16 | 3.3 / 4.4 | 8 | 45 |
| Ryzen 9 4900HS | 8 / 16 | 3.0 / 4.4 | 8 | 35 |
*Specs are unconfirmed.
The true eye-opener with the Ryzen 9 5900HX is the “HX” suffix, which AMD hasn’t utilized up till now. The “H” logically refers back to the H-series chips which can be AMD’s high-performance 45W elements. The chipmaker later launched the HS-series, whereby the “S” denote that it is for slender gadgets. HS-series processors are restricted to a 35W TDP and include barely decrease clock speeds.
Nonetheless, the “X” suffix is actual thriller. We now have two theories. It may both check with an excellent greater clocked model of the H-series with a extra beneficiant thermal restrict, or maybe it is AMD’s means of claiming that the chip has an unlocked multiplier for overclocking.
The Ryzen 9 5900HX’s different specs reportedly embrace a 3.3 GHz base clock and 4.59 GHz increase clock. By way of clock speeds, the Ryzen 9 5900HX seems to function the identical base clock because the Ryzen 9 4900H. Nonetheless, the unreleased Cezanne half does boast a 200 MHz greater increase clock velocity along with twice the cache.
In accordance with Geekbench 5, the common single-and multi-core scores for the Ryzen 9 4900HS are 1,092 and seven,072 factors. We would want extra Ryzen 9 5900HX submissions to have a extra correct concept of the efficiency distinction. Nonetheless, if we solely take this single submission as some extent of reference, the Ryzen 9 5900HX delivered as much as 30.3% greater single-core efficiency. The margin roughly aligns with what the Ryzen 7 5800U presented over the Ryzen 7 4800U.
Within the case of the Ryzen 9 5900HX, the Ryzen 9 4900HS truly got here out on high by 2.3% within the multi-core take a look at, suggesting that this may be a bugged run. Bearing in mind the large single-core margin during which the Ryzen 9 5900X put up, it is not possible that it could lose to the Ryzen 9 4900HS in multi-core efficiency.
