AMD Ryzen 4000 CPU + Radeon RX 5600M/5700M sono in arrivo per i computer portatili – I miei pensieri
So lets find out what this means, what improvements we can expect and how performance could stack up to the Intel and Nvidia competition.. Il nuovo Ryzen 4000 series CPUs are based on the Zen2 7nm architecture, so same as the desktop 3000 series chips that came out last year. Like in the past AMD, have broken the CPUs down into U and H series., U, processors are meant to be lower powered For thinner and lighter machines, while H series chips would be for larger, higher powered devices.. If we take a look at the processor, lineup weve got a couple of H series CPUs and a bunch of U series. Chips. Lets start out with the H CPUs. In the H series: Theres, il Ryzen 5 4600H with 6 core e 12 threads and the Ryzen 7 4800H with 8 core e 16 Discussioni. Il suo valore, noting that the max boost clock listed will be for single core. So definitely dont expect these speeds from multicore workloads.. There are also apparently lower powered S versions too ASUS, in particular, noted the use of the 4800HS in their new G14 gaming laptop.. From my understanding this is the same CPU as the 4800H, but with a lower 35 limite di potenza in watt, but I didnt get too many details.. I found it interesting that theyve got an 8 Core 16 thread part with just a 15 Watt. Power limit obviously were expecting lower clock speeds.. The 4.2GHz quoted here is the same as the 45 watt 4800H, but its just single core.
So that could be feasible. It will be interesting to see how it actually performs in multicore workloads.. I could still see it as being a benefit as more and more apps start to take advantage of more cores, even if they are lower powered compared to a higher power limit 4 o 6 core CPU for instance. AMD are claiming a big boost to multicore performance When strictly comparing performance within that 15 watt power range. Ad essere onesti, the base clock of the 4800U is a full 1.1GHz below the 4800H, which has the higher 45 limite di potenza in watt. But without testing we dont know what speeds to expect base clock should be worst case. I cant recall testing any gaming laptops that ran at base. Orologio. AMD are showing it dominating one of the best 10nm Ice Lake options from Intel in Cinebench Multicore as Ice Lake. U series tops out at 4 Core 8 Discussioni, Tuttavia, even single core had a slight edge with Ryzen.. The Vega graphics on the Ryzen chip is also apparently beating. Intels new Iris, grafica – and these are the AMD provided results showing the differences in different workloads. Its important to take all of these graphs with a grain of salt as theyre always looking to make them look good. We wont know for certain until we get some of these laptops for independent review and testing.. Finora, theres no word if overclocking or undervolting will be supported. That would be cool but Im not getting my hopes up.
I guess well see. Its also worth noting that the memory speed supported by the Ryzen 4000 series is DDR4 3200, which is a significant increase over the previous Ryzen platform limitation of DDR4 2400, and this should also assist with boosting performance over last gen.. Unlike the desktop Ryzen processors, the mobile ones are still using PCIe 3 piuttosto che 4, but thats not a big deal here, but does mean no faster PCIe. 4 storage for laptops. Its great that these AMD laptops are able to offer FreeSync for a smoother tear free gaming, Esperienza. Im, not one hundred percent sure how this works. But it must be the Vega graphics within the CPU that are wired to the display, because FreeSync is still possible in laptops with an AMD CPU but Nvidia GPU. It only seems to be Intel based laptops that arent offering this feature to use G Sync. Per esempio, the Intel integrated graphics needs to be disabled., So when can we expect to see Ryzen 4000 laptops Well for now, AMD have just mentioned Q1, 2020. Allora, Fondamentalmente, between now and the end of March, I havent yet been contacted regarding reviewing any new laptops with any either.. I found it interesting that, despite AMDs claims of the Ryzen 4800H beating the Intel i7 9750H in gaming performance that we didnt see any 4000 series CPUs in any higher end refreshed laptops at CES.. It could just be that different companies are testing the waters with Ryzen and taking it slow.
But personally I think this is a little telling.. These guys would have had the new chips available for some time for testing to create their new products. So the lack of higher end laptops based on Ryzen 4000 mobile chips, kind of leads me to believe theyre, not quite beating Intel yet either in terms of performance power, draw or cost, ma questo è. Just my guess.. If that wasnt the case, then why are there only low to mid range laptops at CES with Ryzen 4000? The best one I saw would be the ASUS G14 with 2060 Max Q. I dont think there are any with 2070 or above for instance.. I guess it could be due to the possibility of new Nvidia graphics being on the way, so maybe they wanted to hold off well have to wait and see.. In addition to new CPUs AMD also announced the 5600M and 5700M graphics for laptops. Tuttavia, very little information was actually provided and no laptops featuring these graphics were seen at CES this year, at least at the companies I visited. Finora, Ive tested the 5500M in the MSI Alpha 15 and it fell in between the Nvidia GTX, 1650 e 1660 Ti. Tuttavia, it was also running at 85 Watt, mentre il 1660 Ti ran at 80 Watt.. Based purely on this, it makes me think, despite using 7nm Navi, these AMD options will also use more power than the Nvidia competition at the higher end.
. This is important for laptops, as it means they may need better cooling and power delivery, potentially meaning we only see them in larger laptops, but these are just my own thoughts and speculation..
