At CES 2023, AMD took the wraps off 5 new 7000 Collection processor households destined for laptops within the coming months. One of the attention-grabbing households was the Ryzen 7040 Collection ‘Phoenix’ chips as, primarily based on the define specs shared by AMD, they have been the one new laptop computer APUs that characteristic probably the most fashionable charms of Zen 4 CPU cores and RDNA 3 graphics. Now an official spec sheet for the AMD Ryzen 7 7840H exhibits much more element for one of many Phoenix relations. And it is notable for its lack of PCIe 5.0 assist.

If you happen to hit the AMD spec hyperlink within the intro (official AMD’s Chinese language web site), you will note that the 7840H options PCIe 4.0, with 20 native lanes, which all are usable by elements corresponding to graphics and storage. In accordance with AMD, Phoenix chips are destined for ‘Final Ultrathin’ laptops, and whereas many gained’t characteristic devoted GPUs, as an alternative counting on the first rate RDNA 3 onboard graphics, there may be nonetheless a full PCIe 4.0 x16 interface accessible. That leaves a PCIe 4.0 x4 hyperlink for a CPU-attached M.2 NVMe slot.
On the subject of the onboard RDNA 3 graphics, the most effective Phoenix chips will characteristic 12 CUs (768 stream processors), working at as much as 2.9GHz; this configuration is dubbed Radeon 780M by AMD. Now we have already seen some early 3DMark Time Spy benchmarks of this iGPU in motion, and it was about 25% quicker than its predecessor (RDNA 2 structure Radeon 680M). In these exams, it was roughly on par with the GeForce RTX 2050 laptop computer GPU.
One other attention-grabbing side of AMD Phoenix is its reminiscence assist. The Ryzen 7 7840H specs present that it helps each LPDDR5 and LPDDR5x Ram sorts, and the native speeds supported are DDR5-5600 and LPDDR5-7600. In the meantime, the reminiscence controller seems to facilitate a capability enhance, with Phoenix chips supporting as much as 256GB of RAM. That is one other characteristic that seems to be an enchancment on the ‘Extremely Fanatic’ focused Ryzen 7045 ‘Dragon Vary’ laptop computer processors.

Another specs confirmed by the Chinese language product data sheets is the CCD die dimension, 178mm2. The L3 cache configuration on this occasion is 16MB. A lot of the different specs have been well-known for the final month, as you possibly can see from the embedded slides from AMD’s CES 2023 presentation, above. Laptops that includes these processors ought to be on cabinets beginning in March.
Keep in mind that AMD Ryzen 7045 ‘Dragon Vary’ chips would be the strongest CPUs within the laptop computer vary, with as much as 16C / 32T Zen 4 cores, with as much as 80MB cache. Nevertheless, this processor will characteristic a small RNDA 2 iGPU, as it’s going to invariably characteristic in gaming and creator laptops with robust discrete graphics options. Additionally, contrasting with Phoenix, Dragon Vary has 28 PCIe Gen 5 lanes (with 24 usable, due to this fact sufficient for an x16 GPU and a pair of x4 SSDs).
