My 4650G from hardwarestore2000 arrived over the weekend and currently posting from it. Bios update was a breeze and so was the updates etc. This is my current passmark results:
Here's my PassMark baseline for comparison. That's with a 4650G running on an ASrock B550M-itx/ac, 16GB of DDR4-3800 c16, 1900 FCLK, 2100MHz iGPU. All in all it's a tad higher, but not much at all. 3D graphics is the only major difference, which is explained by the fact that I've spent a few hours pushing both the memory and iGPU with that express goal. (Note: this is not on an A300, just showing it to compare performance on ITX vs. STX.)Link didn't seem to post: https://www.passmark.com/baselines/V10/display.php?id=130676517316
Running the 4650g with 32gb of 2600 RAM (I will be running VM's on this so top speed isn't an issue) and a 1TB M2 SSD. Hoping I can figure out a way to get more storage to the device other than a 1 or 2 TB laptop drive but that's for another day.
On Lenovo Ideapad Slim 7 with Intelligent Cooling, 4800U pull about 25W, the Cinebench 15 score is about more or less the same with 4650G that pull about 88W.
On long time running, all cores in 4800U runs about 2.5 GHz, don't know, about 4650G, I guess the performance won't different a lot, maybe 4650G faster about 10%-20%.
My 4650G scores ~1510-1530 in CB15, but unlike a U-series laptop it can sustain that performance indefinitely. It's not hitting anywhere near 88W running these tests - the maximum CPU package power recorded in HWinfo64 is 55W. CB15 for me runs at a sustained ~4.11GHz all core btw.25W is the long term power draw, not the boost power draw (that can reach into the 40W range) - and as I said, Cinebench mostly finishes within the boost window. Just look at how dramatically performance drops off after the first few CB runs in NotebookCheck's review, starting at ~1620 but then dropping to ~1210. The 4650G has a base clock of 3.7GHz, so in workloads that aren't limited by anything but clock speed it should be ~25% faster. Of course the IdeaPad/Yoga Slim 7 also IIRC runs LPDDR4x-4233, which is significantly faster than any DDR4 you're likely to run on a 4650G. So if the workload responds well to memory bandwidth, that is definitely an advantage for the mobile chip.
