AMD Ryzen 7 5800U "Cezanne" Based on "Zen 3," Geekbenched
AMD's main competitor to Intel's 11th Gen Core "Tiger Lake" processor in the mobile space, the Ryzen 5800U, will introduce the same kind of generational IPC improvements over the Ryzen 4800U "Renoir" as the Ryzen 5000 desktop processors introduced over their Ryzen 3000 predecessors. Based on the 7 nm "Cezanne" silicon, the new Ryzen 7 5800U processor was put through Geekbench 5.1.1, where it yielded performance numbers of 1491 points single-threaded, and 6450 points multi-threaded. HotHardware comments that these numbers reflect a major IPC increase.
With the Ryzen 5000U series, AMD is taking a very confusing approach to the processor model stack, with half the parts based on the older "Zen 2" microarchitecture and "Lucienne" silicon, and the other half "Zen 3." The model number scheme goes as 5x00U, where if "x" is an odd number, the chip is "Zen 2" based, and if it's an even number, it is "Zen 3" based. For example, the 5800U is based on "Zen 3," whereas the 5700U is based on "Zen 2." Find the 5800U Geekbench 5 validation here. The Geekbench database listing also confirms that much like with the 8-core "Zen 3" chiplets on the Ryzen 5000 "Vermeer" desktop processors, "Cezanne" features an 8-core "Zen 3" CPU that does away with the 4-core CCX arrangement, and features a single 8-core CCX with a monolithic 16 MB L3 cache—a doubling in overall L3 cache amount compared to "Renoir," and a quadrupling in addressable L3 cache by each core.

I'm curious why you posted an image instead of a link to the actual result.Sorry, ADD here :-(
Damn COVIDs.
4800U+16GB of LPDDR4X appears to be exceptionally rare in the EU and realistically, I like UK keyboard layouts over US-Intl.
Even if the scores are better when it's released, the M1 will still have more efficient cores.
The native version of Chrome scores a 207 in Speedometer 2.0 on the M1 Mac mini. Ryzen 5950X scores a 140. 10900k scores a 119.
So much for the "PC master race."
Even though I hate macOS, I'm thinking of switching to an M1 Mac. You can't buy a PC that's as efficient as an M1 Mac. The CPU and GPU are both more efficient than anything AMD, Intel, and Nvidia have to offer. Alder Lake and Cezanne won't change that. They'll also likely be going up against Apple's M2 chip since Apple probably will update their M chips annually just as the do with their A chips.
PC users are going to be raging over Apple's desktop hardware dominance for years. Apple is prioritizing efficiency over flexibility. The PC will always prioritize flexibility over efficiency.
I'm pleased that the M1 is doing really well. It might convince Intel/AMD/Microsoft to finally update x86 and create a newer, more streamlined architecture (that can still emulate legacy instructions).
Nice bait post though
Enjoy your inferior technology.
The M1 shows that there is tons of potential but it isn't a simple RISC based cpu. It has many co processors attached from what I gathered (please correct me if I'm wrong).
Cezanne is just Renoir with Zen3 instead of Zen2
Rembrandt (expected 2022) is when the APUs finally get rid of Vega, and it'll be long overdue by then (hell, it's already overdue now given that the alarmingly-rare Vega8 is struggling to match the Xe IGP that's going into a large proportion of Intel's new laptops. A cut down Vega6 and slower DDR4 is just a further blow to the dated Vega IGP).
looking at the Pcmr outlook, 3-400 watt GPUs and 8/64 logical cores at upto 1-300 watts.
Capabilities to play cod at 1/8K I think anyone chasing efficiency alone is missing the curve, unless using Chrome is your sole use case @techisfun hopefully you will enjoy your forum trolling for even longer per day with your M1, noice.
If you can't handle facts, just ignore my posts and stay in your bubble.
Let's wait for comparative benches, then the Pcmr can still ignore it as irrelevant because it always was ,a walled garden anyway and many other reasons too.
Pcmr doom ,. Err nah the Mobil industry said that years ago ,apple are now , last year Google stadia azure and Aws were killing off the Pcmr but still no one can buy a new GPU today.
I could buy a Mac, but muhaha no I'm not getting my ass slapped by apple tyvm.
M1 is a CPU where all design choice were targeted to end users.
Zen X CPU are cpu where design choice are made to be able to be the Jack of all trade (end users, server, workstation, etc.).
On intel side, they are looking to have multiple design. Some will have high single thread performance, other will be computation oriented, some server.
I say that because Apple made all design choice to make their CPU as efficient as possible and get as high as possible single thread performance as it's the best option for the case they CPU will be used.
AMD on other end, made choice to be good in many scenario. They don't have the budget like intel to have 1 architecture for server, 1 for workstation, 1 for desktop, 1 for laptop etc... So they had to apply the Zen sauce everywhere. This means they make choice of having a mix of multithread and single thread optimisation in their design choice. And this is showed because AMD outclass big time the M1 in multithread performance.
Also, We have to consider that M1 CPU is on 5nm node where Zen3 is still on 7nm. So It's Expected that they can deliver more performance and efficiency as they can have more transistor with better power efficiency.
M1 is great, people saying that arm suck are blindfolded. An ARM cpu designed with laptop/desktop user in mind will indeed perform well (like an arm CPU designed for Hyperscaller perform well in these scenario). But in the end, people put way too much fanboyism on that. Arm and x86 both now have front end decoder, both use SIMD, etc...
I really don't understand where your hostility is coming from. Apple won. AMD, Intel, and Nvidia lost. Get over it.
Here is M1 running x86 based Geekbench. Not so much more powerful now, is it? Consider also that it is built on a superior node and you'll see that it's not that big of a deal. It is simply doing well in what it was designed for. No surprise there.
