Throughout a time of elevated competitor exercise, Intel has determined to reveal a number of the excessive degree particulars surrounding its subsequent era shopper processor, often known as Rocket Lake or Intel’s 11th Gen Core. The brand new processor household is due available in the market within the first quarter of 2021, and is predicted to share a socket and motherboard compatibility with the present 10th Gen Comet Lake processors, offering an improve path even for these with a Core i9-10900Okay, Intel’s highest performing desktop processor so far. New 500-series motherboards are additionally anticipated to be accessible.
The brand new Rocket Lake-S silicon or SoC goes to be often known as ‘Cypress Cove’. Intel confuses itself within the press launch in comparison with the PDF presentation, because the press launch dictates that this isn’t the core – it particularly states that the core microarchitecture is Ice Lake (Sunny Cove). Nevertheless the presentation PDF says Cypress Cove is the core. On this occasion, to be clear, Sunny Cove and Cypress Cove are set to be virtually equivalent, nonetheless Sunny Cove is on 10nm and Cypress Cove is the back-ported variant on 14nm.
Paired with these cores would be the Tiger Lake graphics structure, often known as Xe-LP, which can be being backported from 10nm to 14nm for this product. The mixed 14nm illustration of Ice Lake cores and Xe-LP graphics is what will be often known as Rocket Lake, (a minimum of considered one of) the SoC(s) of the 11th Gen Core household.
With the brand new processors, Intel is concentrating on a uncooked instruction-per-clock uplift within the double digit vary, which might be much like the uplift we noticed transferring from Comet Lake to Intel’s Ice Lake cellular processors. Due to the node distinction, the precise IPC change is more likely to be decrease than what we’ve seen earlier than, however 10%+ remains to be extremely respectable, particularly if Intel can be capable of keep the excessive frequency it has achieved with the present era of Comet Lake.
One of many advantages of transferring to a back-ported Sunny Cove core would be the inclusion of the AVX-512 vector acceleration unit in Cypress Cove. This allows Intel to allow its library of Deep Studying Increase applied sciences for AI and ML acceleration, together with help for Vector Neural Community Directions (VNNI), lastly bringing AVX-512 to the desktop platform.
Nevertheless, to combine and match the precise mixture of core depend, graphics, and AVX-512 for die dimension/yield/value, it seems that Rocket Lake-S will solely supply a most of eight cores in its largest configuration. Throughout the press launch PDF, Intel said that the present silicon as examined is rated for 125 W TDP, with a high turbo increase of 250 W, which matches what we see on the Core i9-10900Okay already. There’s no escaping the performance-per-watt traits of the method node, which signifies that Intel would possibly discover hitting these excessive frequencies a bit simpler with fewer cores to cope with. Intel can be selling new overclocking instruments with Rocket Lake, nonetheless didn’t go into particulars.
One other function that Intel has disclosed with Rocket Lake is the transfer to PCIe Gen 4.Zero on the processor, with as much as 20 lanes accessible. These are more likely to be break up into one x16 for graphics and one x4 for storage on most motherboards, and this aligns with what we’ve seen on the most recent era of Intel Z490 motherboards, a few of which have already promoted help for PCIe 4.0 ‘on future Intel processors’. This implies Rocket Lake. Intel additionally mentions that the reminiscence controller now helps as much as DDR4-3200, nonetheless the projected efficiency numbers had been executed with DDR4-2933 reminiscence.
On the graphics facet, transferring to the Xe-LP graphics structure goes to be an enormous uplift in graphics efficiency, with Intel suggesting a 50% enchancment over present Comet Lake built-in graphics. It’s price noting right here within the slide that Intel mentions ‘UHD Graphics ft Xe Graphics Structure’ – this is able to maybe level to a scaled down model of Xe in comparison with Tiger Lake. I’m absolutely anticipating to see solely 32 EUs right here, as a steadiness between die space, energy, and efficiency. Within the advantageous print it means that there will probably be some variations of Rocket Lake with out the built-in graphics enabled, much like the F processors we see available on the market right this moment.
That being mentioned, for these models with built-in graphics, Intel is selling new media encoders and show decision help, with as much as 4K60 12-bit for 4:4:Four HEVC and VP9, or as much as 4K60 with 10-bit 4:2:Zero AV1, showcasing AV1 help for mainstream processors. Show decision help has additionally elevated, with as much as three 4K60 shows or two 5K60 shows, supporting DP 1.4a, HDMI 2.0b, and HBR3.
This was an sudden information announcement this morning. Will probably be attention-grabbing to listen to if Intel will disclose extra particulars forward of launch.
