After months of ready and hypothesis, Intel lastly introduced its 14th Gen Meteor Lake structure. With a plethora of enhancements, together with higher energy effectivity, AI at scale, and new E- and P-core microarchitecture, the chipset household has just a few upgrades up its sleeve. Nonetheless, one of the vital distinguished developments got here from graphical energy. Intel now brings its Arc GPU help to 14th Gen Meteor Lake chips by way of built-in graphics. Study all about Intel Arc within the 14th gen under.

Ever since Intel Arc graphics got here out, one in all its largest upsides was elevated sport body charges. Nonetheless, that was all the time restricted to a devoted GPU format. That modifications with Meteor Lake, as Intel Arc is now infused with built-in graphics to raise gaming and different use instances. This, in flip, will present dramatically improved body charges.

New Intel Xe LPG Structure with {Hardware} Ray Tracing

The vastly improved graphical efficiency has been made attainable with the brand new Xe LPG structure current on the disaggregated structure. LPG is a mix of the corporate’s earlier Xe LP iteration together with its HPG structure. The brand new structure additionally fulfills Intel’s objective of providing 2x the efficiency from the earlier era.

Moreover, this has influenced the brand new Xe LPG structure and given options by no means attainable in chipsets. This consists of help for DX 12 Final, VRS, {Hardware} Ray Tracing, Sampler Suggestions, and extra. Intel claims that “every little thing you’ve come to anticipate from high-end graphics is now accessible in Meteor Lake Chips.” And sure, you learn that proper, Intel Built-in graphics will include {Hardware} Ray Tracing (extra on this under) for the primary time.

Intel Xe LPG Makes use of Tri-Fold Strategy

The brand new Intel Xe LPG engine that powers the magic behind Arc has been scaled to make sure it meets the corporate’s imaginative and prescient. This has been performed by way of a tri-fold strategy specializing in larger clock frequency, bigger GPU configuration, and general ‘structure effectivity.

The LPG structure runs at larger clocks at any voltage and on decrease voltage at any explicit frequency. The corporate mentions that the decrease voltage is essential because it has allowed Intel Meteor Lake to ship 2x perf/watt. Moreover, that is additionally one of many first instances the corporate has used machine studying for timing closure. This ends in additional energy discount.

Intel Is Utilizing Extra Silicon Space to Energy Arc

Inserting extra energy right into a chip will naturally require extra actual property. The corporate revealed it makes use of a wider GPU configuration by utilizing extra silicon space to energy the graphics engine. To place it into numerical phrases, the brand new 14th-Gen Meteor Lake GPU tile is 30% bigger. One other new addition is the added 8 Xe cores, that are the computational blocks. The chip additionally comes with 128 Vector items in comparison with final yr’s 96.

Nonetheless, the present’s stars are undoubtedly the brand new 8 Ray Tracing Items, which, as acknowledged above, deliver help for {Hardware} Ray-Tracing to Intel’s built-in graphics for the primary time.

Intel has additionally targeted on architectural effectivity. The Xe Core incorporates 16 256-bit vector engines. The core possesses 192KB of shared L1 Reminiscence. It may be configured as a SLM (Shared native reminiscence) or act as a cache altogether. Intel is utilizing the identical type configuration for Arc GPUs. This has been performed for synergy and to deliver a way of software program stability. Intel believes this can assist software program builders have a typical platform, which can assist the brand new built-in graphics.

Meteor Lake Deliver DX 12 Final & Ray Tracing Assist

In addition to the above computational enhancements, one of many largest bulletins is the inclusion of DX 12 Final and Ray Tracing in Intel’s 14th Gen Meteor Lake. The help for native DX 12 will deliver options like {hardware} Ray-Tracing, mesh shading, VRS Tier 2, and sampler suggestions.

Intel's depth test

Whereas Intel didn’t share any precise metrics, it did share some architectural exams testing the brand new Xe LPG in opposition to LP in just a few exams. As you may see your self, the brand new Xe LPG scores virtually 7x larger within the Depth take a look at. The identical sample is repeated in Vertex Processing, Triange Draw Price, and extra.

Intel showcased the identical at its Intel Tech Tour Malaysia 2023 behind closed doorways, the place the corporate confirmed a gameplay video of Forza Horizon 4 working at a clean 50-60 FPS by way of the onboard Intel Arc graphics. Whereas the sport setting and machine configurations weren’t revealed, the demo seemed extraordinarily clean with no stutters. This efficiency ought to carry over to different well-liked video games because the chips slowly roll out.

Ray Tracing Comes with Extra Use Circumstances In addition to Gaming

Ray Tracing, however, lastly makes its entry into Intel’s Meteor Lake. The corporate confirmed the identical when speaking about HW RT use instances. The corporate showcased UL’s new Photo voltaic Bay benchmark, displaying that the brand new built-in graphics can do ray tracing in actual time. Mixed with the breadth of enhancements above, this means Meteor Lake efficiently utilizing HW RT in future functions. Nonetheless, that’s not the one use case of Intel’s new LPG.

Creators additionally get a large enhance as now you can run Blender on Intel’s 14th Gen Meteor Lake chips. That is partly resulting from Intel’s position in Embree, its RT library, which has {hardware} ray tracing help. Since Blender additionally makes use of Embree, customers will now have the ability to run the software program proper from their chipsets. Intel confirmed off some {hardware} ray tracing Blender figures. As seen, the outcomes present virtually 3 times quicker efficiency in contrast with conventional CPUs.

As its final use case, Intel additionally believes there are various extra sensible functions in Ray Tracing and is, therefore, doing its personal analysis into making that attainable.

Intel Endurance Gaming Offers Optimum Gaming on Battery Life

Whereas gaming on a laptop computer’s battery is the very last thing it’s best to do, Intel acknowledges the necessity for transportable gaming. As such, the built-in graphics on the brand new 14th Gen Meteor Lake will include Intel’s new Intel Arc Management software program. It will function the management panel that lets customers regulate modes for Intel’s Endurance Mode, a brand new characteristic designed to handle energy with graphics dynamically.

Customers will have the ability to choose from three totally different modes that may cap body charges accordingly whereas offering a steady battery life. Intel confirmed the identical because it introduced stats whereby Rocket League ran with simply 1W of energy, which is wonderful.

In addition to the brand new graphical enhancements, Intel additionally make clear its disaggregated structure, which incorporates the Xe Media Engine, which helps as much as 8k @ 60 10-bit HDR decode. Intel additionally mentioned the new Xe Show Engine, which has 4 pipes for a number of shows and extensive help for HDMI 2.1, DP 2.1 20G, as much as 8k @ 60 HDR, QHD, FHD, and extra.

With {hardware} ray tracing coming to built-in graphics for the primary time, Intel’s 14th-Gen Meteor Lake lineup can be wonderful. Full of 2x efficiency per watt and extra energy effectivity, the Arc inclusion can be thrilling. Solely time will inform what real-life efficiency we will anticipate from Intel’s Arc graphical platform.
