, kako se stvari okreću u Intelu.

Da, tak bome ispada, a ovaj Robert Hallock jučer samo da nije briznul u suze od jada i to još kad ga dvojica "novinara" s probranim pitanjima, drže za ruku dok idu prek ceste zvane Arrow Lake. Tip je u jednom trenutku na rubu suza pričal o tome kak oni u Intelu jako brinu o svemu, nije ni njima svejedno da se ovo događa i da su ljudi nezadovoljni, a i on sam je svoju osobnu gaming mašinu prebacil na 285K i baš uživa u 1440p gamingu. Mislim si, pa čak da je sve ovo kaj je pokazal u opet standardnim Intel PowerPoint slajdovima - istina - sad ste već došli do siječnja 2025., ali nema konkretnog datuma. Kad stignu zakrpe negdje tokom siječnja, taman budu izašli 9950X3D i 9900X3D i onda bude Robert opet (pod uvjetom da ostane u firmi) moral u neko unaprijed pripremljeno i dogovoreno podcast gostovanje da objasni kaj se desilo s onim očekivanjima za siječanj 2025.

Arrow Lake Retested with Latest 24H2 Updates and New BIOS

Citiraj:

In today's article we benched five configurations: 23H2 from October, 23H2 with the newest updates till today, and also added the newest ASUS BIOS into the mix, which includes the 0x113 microcode (not 0x114 yet). Then, we moved on to test Windows 11 24H2—first with a fresh installation that had no chance to update, so it lacks the KB5044384 package that includes Intel's fixes to the processor's power management profile. Finally, we updated Windows 11 24H2 with the newest everything, including KB5044384 and all other patches released this month. Just to clarify, in addition to "23H2 with new BIOS", all Windows 11 24H2 tests were done with the 1101 BIOS, too, which includes microcode 0x113. Our application results confirm that Intel has definitely improved things with their PPM update. Especially when comparing 24H2 only, the differences are noteworthy and bring much-needed performance improvements. However, compared to Windows 11 23H2, we see no meaningful advancements overall.

However, the whole claim is "6-30% (estimated)", which would suggest you'll see at least 6% in a majority of workloads—this is definitely NOT the case. Overall, the 285K cannot gain enough performance to make it a clear winner vs AMD's Ryzen 9000 lineup, or even 14900K Raptor Lake (it improves power consumption considerably though). Looking at the big picture, the 285K flagship remains slower than even the previous generation mid-range chip, the Core i5-14600K. It seems that Intel did not "fix Arrow Lake," but they "fixed Arrow Lake on 24H2". No doubt, fixing your product's performance in the newest OS release specifically is important and a solid improvement—why isn't the company transparent and makes that clear in their messaging?

Intel Core Ultra 9 285K "Arrow Lake" Windows 11 vs. Ubuntu Linux Performance

Citiraj:

From the benchmarks today it's looking like the Intel Core Ultra 9 285K CPU performance is fairly stable from Linux 6.11 through 6.13 kernels with no major performance shifts besides some subtle variation. Across the span of 92 benchmarks carried out, Ubuntu 24.10 was about 6% faster than Windows 11 24H2 for this out-of-the-box / default comparison. All the benchmarks in full can be found here. There was little benefit to the performance itself from switching out the Linux 6.11 default kernel on Ubuntu 24.10 to using Linux 6.12 LTS stable or Linux 6.13 Git, but the newer kernels can provide some features and hardware support such as if you'll also be going for Intel Arc B-Series graphics, for example. It was surprising to see the Intel P-State performance governor providing little help for the Core Ultra 9 285K compared to the default powersave governor. Typically the performance governor allows for more headroom but wasn't the case here with the Core Ultra 9 285K and ASUS motherboard.

Intel Arrow Lake 0x114 Microcode Already Out, No Significant Gains—We Tested

Citiraj:

Motherboard vendor ASUS began rolling out UEFI firmware (BIOS) updates to its Intel Z890 motherboards that contain Intel's 0x114 Microcode update for Core Ultra "Arrow Lake-S" desktop processors. The new microcode was touted as bringing in performance gains to gaming workloads across the board, with Intel saying that depending on the configuration, one could expect a "roughly 3-8% performance gain." The company said that motherboard vendors should begin releasing BIOS updates with 0x114 "starting January 2025," however, it seems like ASUS is ready with public "stable" (non-beta) BIOS updates with it. We use a ROG Maximus Z890 Hero in our "Arrow Lake-S" reviews, and so promptly grabbed the version 1203 BIOS from the ASUS website, and put it to the test. This also updates Intel ME (management engine) to v19.0.0.1827.

We added our performance testing numbers to our article from yesterday (December 19, 2024), where we had tested the Core Ultra 9 285K with the latest OS-level patches for Windows 11 24H2. Long story short, we do not notice any notable performance gains with the 0x114 microcode update. 0x114 was touted as providing users with additional performance gains after all the OS- and BIOS configuration related issues had been fixed. In its pre-brief from earlier this week, Intel said that the 0x114 microcode update represented additional performance gain opportunities that the company had discovered in the process of identifying and fixing the reasons why the processors fell significantly behind Intel's performance guidance in their launch reviews in October.

100+ Linux Benchmarks Of Intel Arrow Lake With New BIOS / 0x114 CPU Microcode

Citiraj:

There were no major changes in performance with the new ASUS BIOS featuring the 0x114 CPU microcode. A number of Phoronix readers inquired though the past few days if these Intel updates would further enhance Arrow Lake performance on Linux, but at this stage it appears not to across the 100+ benchmarks used. We'll see if the second round of updates in January mean anything for the Core Ultra Series 2 Linux performance. With the geo mean of over 100 benchmarks, the results were flat. Those wanting to jump through all of the unchanged Linux benchmark data can find this fresh data via this result file.

Vendors push Intel's promised performance-boosting firmware for Intel Arrow Lake CPUs

Citiraj:

Intel partners have started to deploy BIOS patches for Z890 motherboards featuring the 0x114 microcode coupled with the updated CSME 1854v2.2 firmware. The patches serve as the last piece to Intel's Core Ultra 200S (Arrow Lake) performance puzzle, with the newer CSME and BIOS combo promising additional single-digit increases in gaming performance.

In a report issued a few days back, Intel reportedly addressed four of the five root causes that held back performance. As a follow-up, Intel promised further performance enhancements through BIOS firmware updates by January, alluding to the long-anticipated 0x114 microcode. While that specific microcode has been in vogue for some time in the form of beta BIOS releases, Intel says that the final update requires both the updated microcode and a specific CSME Firmware Kit (19.0.0.1854v2.2 or newer), which is now available.

While Intel has addressed most of its underlying issues with Arrow Lake through Windows 11 updates, driver patches, and newer BIOSes, the final update should yield users a small additional bump in performance. We might see stable BIOS builds with the new 0x114 microcode and updated ME firmware from board partners by early January or even in a couple of days as they iron out the remaining quirks.
