AMD Rembrandt Mobile

AMD announced Rembrandt 6000-series mobile processors with Zen 3+ CPU cores and RDNA2 integrated graphics.

The 8-core processors (e.g. 45W Ryzen 7 6800H and 15W Ryzen 7 6800U) all have 12 RDNA2 graphics cores (CUs), up from the previous generation Cezanne's 8 Vega graphics cores. This could mean a doubling of graphics performance. On the other hand, the 6-core processors (e.g. 15W Ryzen 7 6600U) slash this in half to only 6 RDNA2 CUs.

Rembrandt uses DDR5 or LPDDR5 memory and adds support for 40 Gbps USB4 ports, PCIe Gen 4.0 GPUs and storage, HDMI 2.1 and DisplayPort 2, and AV1 hardware decode.

There are also three "Barcelo" models which are refreshes of Cezanne chips (8-core Ryzen 7 5825U, 6-core Ryzen 5 5625U, and 4-core Ryzen 3 5425U).

Rembrandt will be one of the first products to integrate Microsoft's "Pluton" security chip.

Intel Alder Lake Mobile

Intel announced Alder Lake-H (high performance) and Alder Lake-U (low power) mobile processors, with a heterogeneous microarchitecture featuring performance (P) and efficiency (E) cores.

Alder Lake-H has a "base power" of 45 Watts and a "max turbo power" of 115 Watts. The top i9/i7 chips have 14 cores (6P + 8E). In the middle there is an i7-12650H with 10 cores (6P + 4E) and an i5-12600H and i5-12500H with 12 cores (4P + 8E), so that may lead to some confusion. Finally, there is an i5-12450H with 8 cores (4P + 4E).

Alder Lake-U has a "base power" of 15 Watts and a "max turbo power" of 55 Watts. At the top there are a few chips with 10 cores (2P + 8E) and 80 or 96 graphics execution units (EUs). The i3-1215U has 6 cores (2P + 4E) and 64 EUs. Finally there are a Pentium 8505 and Celeron 7305 with 5 cores (1P + 4E) and 48 EUs.

More

* Intel announced cheaper and lower power Alder Lake desktop CPUs, including CPUs made from a smaller die with no efficiency cores, and the world's fastest dual-core CPU (the Pentium G7400).
* AMD announced the Ryzen 7 5800X3D for a Spring 2022 launch. No other Zen 3 CPUs with stacked cache are planned.
* Zen 4 and the AM5 socket will launch sometime during the second half of 2022.
* AMD announced the RX 6500 XT ($200) and various mobile GPUs.
* Nvidia announced its RTX 3050 ($250) and RTX 3090 Ti desktop GPUs

AMD Details Ryzen 7000 Launch: Ryzen 7950X and More, Coming Sept. 27th

Driving AMD's gains in this newest generation of desktop CPUs is a combination of architectural improvements underpinning the Zen 4 architecture, as well as moving production of the CPU core chiplets to TSMC's leading-edge 5nm process. The combination of which will allow AMD to deliver what they are saying is now a 13% increase in IPC over their Zen 3 architecture – up from an 11% claim as of Computex – as well as a sizable increase in CPU clockspeeds. The top-end Ryzen 9 7950X will have a maximum turbo clockspeed of 5.7GHz, 800MHz (16%) higher than the equivalent Ryzen 9 5950X. As a result, AMD expects to deliver a 29% generational increase in single-threaded performance, and even more in multi-threaded workloads.

Launching in conjunction with the new Ryzen 7000 series chips will be AMD's AM5 platform, which will be cornerstone of AMD's consumer desktop platform through at least 2025. AM5 introduces DDR5 and PCIe 5.0 support for AMD's chips, as well as a new LGA socket. 4 chipsets are planned thus far – X670 Extreme, X670, B650 Extreme, and B650 – with X670 series boards available for the September launch, and B650 series boards set to follow in October.

Ryzen 5 5600X63.7 GHz4.6 GHz65 W24x 4.0$300
All CPUs reserve 4 PCIe lanes for the chipset.
Socket AM5 is compatible with existing AM4 coolers.

While top TDPs have increased to 170W (230W socket power delivery) for the 7950X and 7900X, power efficiency is up. AMD's CTO Mark Papermaster called the 65W TDP a "sweet spot" for TSMC's N5 node, claiming that the 7950X is 74% faster than the 5950X when limited to 65W. This will become relevant to the performance of AMD's "Dragon Range" mobile CPUs, which will simply drop repackaged Zen 4 desktop CPUs with up to 16 cores into high-end laptops.

AVX-512 instruction set support has been added. Frequency drops seen on previous Intel implementations may be avoided due to the design, which "double-pumps" 256-bit instructions. AMD claimed up to a 150% performance increase over Ryzen 5000 (using INT8 VNNI).

The new Socket AM5 is planned to last through at least 2025, with Zen 5 CPUs arriving sometime in 2024. X670 and B650 motherboards use the same chipset, but X670 uses two of them to achieve better signal integrity. The X670E and B650E "Extreme" motherboards will guarantee support for both PCIe 5.0 graphics cards and storage. PCIe 5.0 SSDs will become available in November 2022. AMD believes that DDR5-6000 is the "sweet spot" memory configuration for Ryzen 7000.

All of the Ryzen 7000 desktop CPUs will include RDNA2 integrated graphics with 2 compute units, 128 stream processors (compare to the 6 or 12 CUs found in Rembrandt APUs). The iGPU is located inside the "6nm" I/O die, and supports up to four display outputs, including HDMI 2.1 and DisplayPort 2.0.

Ryzen 7000 models with added 3D V-Cache are rumored to launch in early 2023.

    Seriously, a low power laptop may be alright, because you're less likely to cook the internals. A high power laptop, you may as well get yourself a desktop with actual airflow or expect to replace your laptop toaster in the next year or two.

      The 15W Ryzen 7 6800U looks pretty attractive. If that 15W is real, that should be able to be dissipated in even something as thin as an XPS (my i7 XPS-13 thermally throttles before it even finishes booting up). But, will have to see if the new MS designed "security" processor built-into the new AMD processors (and to be added to Intel and Qualcomm processors too), is some scary back-door / DRM bullshit, in which case, so long AMD and Intel.

        The aggressive cut down to 6 CUs "kills" the 6600U (makes it equivalent to around Cezanne/Vega 8 CUs, I guess). Should make the 8-cores more popular.

        Rembrandt holds the line at 1080p. Going forward, AMD's Phoenix and Strix Point will only improve on that, and further reduce the need for discrete graphics.

        Keep in mind that those U chips are going up to more like 28W in some cases, which they should given sufficient cooling. However some of AMD's slides compared 15W 5800U to 28W 6800U:

        Pluton is bad news. Might be the end of the PC industry as we know it. I don't think it will be in Zen 4, but it will probably be in whatever comes next.

        For those not up on the news, Pluton basically means that Microsoft will have veto power over all software. It's not just secure boot turned up to 11, it's turned up to a billion.

    Neither chipmaker has given any attention to the low end for a couple of generations. GPUs have still been getting faster, but they're getting more expensive at the same rate.

    Of course, it won't actually be available anywhere near retail price, at least not without a lot of effort or luck. But maybe it will take some pressure off the used market. With five year old cards selling for $400, things are really out of hand.

      There's going to be a 3-way at the low end. From AMD, "$200" RX 6500 XT and a cheaper RX 6400 [amd.com] which is official now but was not given a price or release date. Nvidia has the RTX 3050 which will be a target for miners because of the higher VRAM. Then Intel will have 128 execution unit DG2/Arc GPUs which should have 6 GB of VRAM (Tiger Lake and Alder Lake have up to 96 execution unit graphics).

      Considering the "expensive" $300-$400 GPUs have been consistently selling for easy 2X that, it's not like the MSRP has anything to do with the price of GPUs. Even your lower end GPUs saw price hikes. People that would normally buy a more expensive GPU are settling for lower, which means that the person who would normally get someone's used okay GPU is now getting some piece of junk. Either that or just doing without.

        The 6500 XT might fare better than other GPUs for some of the reasons listed there. Like if they really "flood" the market with them, and miners stay away because of the 4 GB VRAM.

        It is a pretty gimped GPU [videocardz.com] though (PCIe 4.0 x4, low VRAM, no AV1 decode). They are daring people not to buy it.

          The low VRAM is necessary to ward off miners, and to keep costs down, but it seems like a really slow GPU in general. Only being x4 PCIe is painful. Sure, it's enough bandwidth to support that low amount of VRAM... But only if you have a CPU that supports it. There are a lot of people with older CPUs in need of a GPU. AMD seems like they want to use it to sell more CPUs. If it doesn't outperform the ancient RX580, and it seems like it might not, it's not actually improving price/performance any more than any other GPU. It will still be adequate for 1080p gaming, but with very little future proofing.

      You are skimping too much on watts. 65W Ryzen 7 5700G or a Core i5-12400 are not hard to cool, and comparable to 1-2 incandescent bulbs.

      The Alder Lake desktop and even mobile iGPU is not great, but if you don't care or are coming from a really old system, it could be just fine.

      What about that Pentium G7400 and Celeron G6900 though?

      What are you doing with a low end CPU that doesn't have an iGPU? Headless file server? There is just not enough market for something like that, especially considering how little cost a low end iGPU adds. Raspberry Pi has an iGPU and the whole computer only needs 10 watts and costs "$5."

        The CPU in question is the i3-12100F at $97. It's a quad-core that would be acceptable for budget gaming builds. It should be one of the fastest quad-cores on release due to IPC gains.

        The i3-12100 with an iGPU is $25 more. That's the pattern for all of the 'F' iGPU-less Alder Lake chips as you can see here [anandtech.com]. So at $97 vs. $122, you're paying ~26% more for a relatively weak iGPU you don't really need if you already have a discrete GPU. It could limit what the CPU can do near the end of its lifespan, and the Alder Lake iGPU could also have better video encode/decode capabilities than the older discrete GPUs people are hanging onto.

        AMD's Zen 4 Raphael desktop chips will be including a small iGPU on some but maybe not all models, so those will be more flexible than previous Ryzen CPUs.

          The 12100F is a promising CPU, but it's 90 watts. In the 35 watt range you are limited to Celerons, which nobody would want for gaming because they are just too slow.

          Basically my point is that nobody wants to put a discrete GPU in a system with such a weak CPU, so if you don't have an iGPU you don't have a display. There are probably a few low end grandma computers with Celerons but most of them end up in embedded applications. Point of sale, signage, kiosks, ATMs. These all need displays. I can't think of many obvious applications that don't need a display but wouldn't be better off with an ARM.

          this.
          also coms between gpu and cpu is Ghz of cpu AND pcie bandwidth.
          the i3 mentioned should do a-okay with 3080, methinks.
          as for low TDP, this and high base Ghz is a very basic indicator that some technological leap was achieved?
          ofc some "quick filling of cpu ram" (dual, quad channel parallalism) also helps when talking/using a massive parallel dGPU?
          seems ram is ddr4 and ddr5 and just dual channel only requiring quick but massive burts of data transfer but less atomic...
