In the news and early reviews, Intel is today formally launched its Core 11-Gen family of desktop processors, moreover linked to as Rocket Lake, designed on Intel’s most advanced 14nm method node technology.
This new product family will form the idea of Intel’s premium desktop portfolio for most of 2021, if not longer, and options processor with up to eight cores. Highlights embrace the new microarchitecture, Cypress Cove, and therefore the Xe-LP graphics style, each of that are redesigns of Intel’s 10nm mobile product.
These elements additionally include Intel’s initial PCIe 4.0, new AVX-512 for desktop, higher memory support and for resizable BAR, new overclocking options, and increased transmission acceleration.
To The Moon With Rocket Lake
With Intel’s processor launches, we generally observe that the new family is all-pervasive, enabling product from the highest Core i9 or i7 elements, all the method down to the Pentiums and therefore the Celerons. Intel sometimes achieves this by building one, two, or additional different sizes of Si, typically differing in cores and graphics to attain the proper balance of value, yield, and performance.
For this generation, Intel has determined to solely manufacture one size of atomic number 14, and section its giving, with the new family solely being employed for i5 and up.
This one-size Si style options eight of Intel’s new Cypress Cove, with HyperThreading, and thirty-two execution units of ‘Core Gen 12’ graphics, derived from Intel’s newest Xe-LP graphics styles. additionally bundled in this Si is a DDR4-3200 memory controller, a PCIe 4.0 root complicated giving twenty lanes for separate graphics and storage, a double-width DMI x8 link to the chipset, advanced AVX-512 for Intel’s Deep Learning Boost technologies, updated overclocking, and next-generation media and show acceleration.
In the past, Intel’s Tick-Tock strategy meant that in every product cycle, either the method node would be updated (tick), or the microarchitecture would be updated (tock). The new Rocket Lake processor, with the Cypress Cove, falls a great deal underneath the ‘tock’ terminology, but this core isn’t a very new microarchitecture by the definition of the word ‘new’.
Backporting 10nm to 14nm
In order to alter Cypress Cove, Intel has taken its Sunny Cove of backporting isn’t as simple as swing the core style on a copier and creating it larger – the impact of the physics of electrons going through wires means there are some inherent style criticalities in this process that deviate it a bit.
However on the total, as our testing has already shown on our retail samples, despite the discussions regarding power, Intel has managed to stay 14nm Cypress Cove as near to the initial 10nm Sunny Cove style as potential.
In a similar mantra, the new Xe-LP ‘Gen12’ graphics on Rocket Lake is additionally the same backport. At this point, Intel has taken the graphics scheme from its 10nm Tiger Lake notebook processor and made it into 14nm.
As a notebook processor Tiger Lake focuses plenty on integrated graphics, and as a result, has ninety-six execution units – Rocket Lake by comparison has only thirty-two units.
Backport vs Co-design
The future of however and once Intel can initiate further backporting, even given advised roadmaps, is probably going to be in flux supported its ability to provide high single frequency desktop processor.
Cypress Cove, by most measures, is a reflex response to a widening gap in Intel’s desktop roadmap and takes a specifically designed for a special method.
Intel is/has/has probably learned tons from this method, however in the future, we are able to expect specific to be co-designed with each method nodes in mind. this is adored Intel’s new stance on ‘enabling the proper product on the proper node at the proper time’.
A co-designed approach, instead of a post-production realization a backport is needed, can mean that future core styles that straddle 2 method nodes are probably to be additional similar and optimized on each process at the same time.
Intel Lake: Core i9, i7, and i5
The Latest Intel 11th generation desktop processor begins with i5, with 6 and 12 threads, through to i7 and i9, each with 8 cores and sixteen threads.
All processors can accept DDR4-3200 natively, and supply 20 PCIe 4.0 lanes in supported motherboards – these lanes can alter graphics and storage direct from the processor, generally in an x16/x4 or x8/x8/x4 combination.
Both the i9 and i7 this point around have an equivalent count - commonly the Core i9 would supply a clear difference, like additional cores, except for this generation, the distinction is additional subtle: Core i9 can supply higher frequencies and thermal rate boost (TVB).
At the top of the stack is that the i9-11900K. Intel has set the 1000-unit evaluation of the i9-11900K at $539.
Note that Intel does this 1k unit valuation for OEMs, therefore the final retail worth is usually $10-$25 higher. this can be well higher than AMD’s Ryzen seven 5800X at $449 September (MSRP), which is additionally an 8-core processor.
Intel is stating that at the side of better gaming performance, this processor also offers next-generation integrated graphics, acceptance for brand-new AI directions, and increased media support for the value differential.
On specifications, we knew most of the i9-11900K from a previous announcement, however these days we learn that this processor includes a base frequency of 3.5 GHz, aboard a peak turbo of 5.3 GHz in Thermal rate Boost mode, 5.2 GHz otherwise on the favored, or 5.1 GHz on non-favored cores. The all Intel frequency is 4.8 GHz in TVB turbo mode, or 4.7 GHz.
Thermal rate Boost is somewhat new to the desktop space, however what it means is that if the processor is below a particular temperature, it'll add an extra +100 MHz frequency throughout turbo. In the desktop processor, this temperature is 70ºC (158F).
That being said, motherboard makers are liberal to ignore this temperature level, and in our expertise, most consumer/gaming motherboards disable that check and permit for TVB in any respect temperatures.
The only processor not obtaining TVB in the i9 family is that the i9-11900T, which is the 35 W member of the family. This processor has 35 W on the box because its base frequency is 1.5 GHz, though it'll turbo up to 4.9 GHz single-core and three.7 gigacycle all-core. These processors usually find themselves in OEM systems and mini-PCs that are additional possible to strictly follow Intel’s turbo recommendations.
All Core i9 processors can accept DDR4-3200, and therefore the specification is that the K/KF processor change a 1:1 frequency mode with the memory controller at this speed.
This processor offers eight cores, sixteen threads, with a single-core turbo of 5.0 gigahertz on the favored core, 4.9 gigahertz otherwise, and 4.6 gigahertz all-core turbo.
As noted in our review, the 125 W TDP on the box means that very little, as we saw 215-225 W peak power draw throughout turbo of AVX2, and 276-292 W peak power draw throughout AVX-512, and motherboard makers typically default to unlimited turbo in any event.
Users going once any i7 or i9 product should look to a decent air cooler or liquid cooler to get the best thermal performance here.
On the subject of memory, the i7 family will support DDR4-3200, but Intel’s specifications are that any non-Core i9 processor should run at a 2:1 ratio of DRAM to memory controller by default, instead of 1:1, effectively lowering memory performance.
This creates some segmentation between Core i9 and therefore the rest, as for the rest of the processor the specification for DDR4-2933 is 1:1.
Despite this technical specification, we can make sure in our testing of our i7-11700K that each one of the motherboards we've got used to date truly default to 1:1 at DDR4-3200.
it'd seem that motherboard makers are assured enough in their memory styles to ignore Intel’s specifications on this.
The Intel Core i7-11700K is $399, which is vital in 2 ways.
First, it's $140 Inexpensive than the Core i9-K. That leaves the Intel i9 high and dry. Unless there’s one thing special therein chip we'ven’t been told that we have to find return retail day on March thirtieth, that’s a huge evaluation difference.
The second is that the comparative AMD processor, the Ryzen seven 5800X, has eight cores and includes a $449 Sep. If each processor were found at these costs, then the comparison is a smart one – the Ryzen 7 5800X in our testing scored +8% in C.P.U. tests and +1% in playtests (1080p Max).
The Ryzen is incredibly a lot of the additional efficient processor, but the Intel has integrated graphics (an argument that disappears with KF at $374). it'll be attention-grabbing to visualize what recommendations individuals come to with that evaluation.
Another difference at intervals between these elements is that the Core i5-11400 and Core i5-11400T have UHD Graphics 730, not 750, which in all probability implies that these are running 16 EU configurations, instead of 32 EU. The Core i5 spreads out plenty with additional offerings, from $157 for the Core i5-11400F, up to $262 for the Core i5-11600K. of these processors have six cores and twelve threads, all have the normal Intel Turbo 2.0, and all DDR4-3200 (2:1) or DDR4-2933 (1:1).
Comet Lake Refresh: Core i3, Pentium
Rather than style a smaller piece of Si on Cypress cove for the quad-core elements and below, Intel has set to mud off the previous generation style and provides it some updated frequencies. this suggests that none of the Cypress Cove enhancements are in these elements, it's merely Skylake refreshed for a sixth iteration.
Everything here continues to be referred to as 10th gen, and it moves up +100 MHz approximately compared to the regular comet Lake elements. The refresh models are given the ‘5’ designation on the top.
The key part during this family has continually been the Core i3-10105F, providing a quad-core processor equivalent to the Core i7-7700K for below $100.
