Intel's DG2 is reportedly heading to mobile first, launching later this year
by Sayan Sen
We reported yesterday that Intel's upcoming Xe HPG-based high-end discrete gaming graphics' (codenamed 'DG2') launch "is right around the corner" which we had learned from a tweet by a Game Developer Relations Engineer at the company, Pete Brubaker. However, Pete, it seems, may have been a bit too bullish with the tweet as a report today from igor'sLAB suggests that we are still quite a while away from DG2's launch and any major announcement outside of a few teases here and there aren't going to happen anytime soon.
The report also adds that DG2 will be mobile-first which means we will reportedly see DG2-based discrete graphics cards first in laptops and notebooks in the latter part of Q4 2021 as Intel is allegedly targeting Christmas time for the launch of these. The two lowest SKUs which are SKU5 and SKU4 are purportedly launching first and they will be paired alongside Alder Lake-P processors. Production of SKU5 and 4 will reportedly start in early Q4. Meanwhile, the three top-end SKUs namely, SKU3, SKU2, and SKU1 are planned for launch next year. You can find the rumored specifications of the five DG2-based SKUs here.
Interestingly, this mobile-first approach is also what Intel took with the DG1 when it launched the Iris Xe MAX graphics for notebooks first while the desktop version came much later.
Intel's discrete gaming graphics (DG2) is apparently "right around the corner"
by Sayan Sen
Intel's upcoming high-end desktop gaming graphics (codenamed DG2) is set to launch sometime this year. In fact, its launch maybe sooner than we think as DG2 is apparently "right around the corner" if a tweet from Pete Brubaker, who is a Game Developer Relations Engineer at the company, is to be believed. Pete has shared a job invitation for the same position on Twitter today and is inviting interested candidates to work on DG2 development.
The DG2 will be based on the company's Xe HPG architecture, something which Intel has been teasing lately with some fun puzzles as well as GPU benchmark runs, and Intel may show more of the DG2 in action at Computex 2021.
From leaks so far, it's known that the company is working on five DG2-based SKUs and the flagship product could offer up to 512EUs and is rumored to offer performance somewhere between an RTX 3080 and the 3070, so we may see it compete with Nvidia's upcoming RTX 3070 Ti or AMD's Radeon RX 6800.
The leaked specifications of the five SKUs are listed below:
Execution Units Memory Capacity Memory Speed SKU1 512 EU 16GB GDDR6 18Gbps SKU2 384 EU N/A N/A SKU3 256 EU N/A N/A SKU4 128 EU N/A N/A SKU5 96 EU 4GB GDDR6 14Gbps Unlike the DG1, which is based on the Xe LP design, and uses Intel's in-house 10nm SuperFin process, Xe HPG will be employing some external process and is rumored to be using TSMC's 7nm lithography.

Here is Linux Advisory Board's ruling on University of Minnesota's "hypocrite commits"
by Usama Jawad
A couple of weeks ago, we reported that Greg Kroah-Hartman from the Linux kernel development and maintenance team had banned submissions from the University of Minnesota (UMN) due to some questionable patches that they submitted. The issue received a lot of public attention particularly due to the email exchanges between Hartman and the student researchers being made public. The latter argued that the patches come in the form of "a new static analyzer", but Hartman took issue with the fact that the clearly incorrect patches had been submitted to the kernel without any warning.
After much back and forth, the department heads for Computer Science at UMN stated that they would investigate the matter further, and soon after, the student researchers published an apology giving more context to their dubious efforts.
Now, the Linux Technical Advisory Board (TAB) has published its own findings of the matter and its recommendations for the future.
In its detailed audit, the Linux TAB has described the entire timeline of events from the time when "one member of the UMN community" began a research project in August 2020 to intentionally introduce flaws in the Linux kernel with fake identities. A research paper on this endeavor was published in November 2020 after which no patches were submitted. Questionable submissions began again in April 2021 which is when Hartman confronted the researchers and eventually banned them from contributing in the future.
Linux TAB has concluded that the researchers broke several documented rules including submitting patches with false identities. Five of these changes were publicly admitted to being invalid by the researchers in their paper, but the TAB has noted that all incorrect changes were caught or ignored by developers and maintainers, which means that its review process works correctly.
435 commits from the UMN were reviewed in total. A summary of findings can be seen below:
Commits found to be correct: 349 Commits found to be incorrect and in need of fixing: 39 Commits already fixed by later commits: 25 Commits that no longer matter: 12 Commits made before the research group existed: 9 Commits the author asked to have removed: 1 In light of the above, the Linux TAB has recommended that moving forward, UMN must improve the quality of its patches. It has also indicated that it will work with researchers to document best practices for contribution to open source projects, including the Linux kernel. It has suggested that the UMN set up its own internal review team, which should consist of at least one experienced developer who validates changes before they are submitted to the kernel. The Linux TAB has cautioned that:
The Linux TAB has emphasized that the research community and kernel developers and maintainers can work in harmony, as they have done so in the past, but the goal of the community should be to create a robust kernel for production use. If efforts like this benefit only the research community, then conflicts such as this can arise, but they can be avoided if the recommendations of the Linux TAB are followed.

Alleged slides containing all details of Intel's upcoming Tiger Lake-H leak
by Sayan Sen
Intel announced its 11th-gen mobile chips from the Tiger Lake family earlier this year at CES. However, back then, the company only unveiled a portion of the full Tiger Lake lineup, an overview of which can be seen in one of today's leaked slides (above) from a new report by HD Tecnologia. The report allegedly has all the leaked slides which are seemingly from the launch presentation of Intel's entire Tiger Lake-H lineup unveil next week.
At CES, Intel announced the quad-core Tiger Lake H35 chips that are built for the ultraportable gaming segment and if the image above is to be believed, upcoming Tiger Lake-H chips will further cover a few more device segments, which include:
Halo enthusiast, Thin enthusiast, and Essential A slide providing a general overview of the improvements and features in Tiger Lake-H outlines features such as the new Willow Cove microarchitecture, support for PCIe Gen 4, and more:
Outside of the quad-core H35 chips previously released, the new report today says that more H-series processors with up to 8 cores are also coming. The biggest difference between these and the previously-announced chips is that they all have more than four cores, so you can probably expect more cooling to be required, thus making for larger devices. The H35 lineup is meant for "ultraportable" gaming. Below is a leaked image that lists all the alleged upcoming Tiger Lake-H SKUs:
Interestingly, while the previous-gen flagship Rocket Lake-H CPU, the Core i9-10980HK, was a 45W part, the new Core i9-11980HK Tiger Lake-H chip might offer a TDP of 65W.Intel also mentions a 35W cTDP for the remaining processors, but it's worth keeping in mind that the frequencies listed alongside that TDP are below the base frequencies that are also listed on the table. It's likely that the chips can be configured down to 35W - like how H35 chips can be configured down to 28W - but their default TDP will still be 45W.
There is another slide outlining the various features of the Core i9-11980HK in detail:
Lastly, a gaming performance comparison has also been provided. Curiously, Intel has seemingly compared its upcoming 6 core Tiger Lake-H Core i5-11400H against the flagship 35W octa-core Ryzen 9 5900HS instead of using the higher end, 35W 8-core i9-11900H. This is probably Intel touting its gaming performance as it apparently matches or beats the Ryzen part with fewer cores.
These leaked slides are all denoted with an embargo date of 11th May which is when we expect Tiger Lake-H to launch. Devices sporting these new chips like the Inspiron 16 Plus from Dell or the Galaxy Book Odyssey from Samsung have already been announced.
