At the ISSCC 2022 conference, Intel revealed details about its ASIC Bonanza Mine, codenamed BMZ1, which is designed for Bitcoin mining.
Interestingly, the presentation was dedicated to the solution of the first generation (BMZ1), while now the company is already supplying customers with the second generation (BMZ2). What is the difference between them and whether the BMZ1 was delivered to customers is unclear.
So, the BMZ1 chip has dimensions of only 7 x 7.5 mm, and the finished system contains 300 of these chips. It is known that these microcircuits are manufactured on a seven-nm process, but there is an opinion that this may be the Intel 7 process, which is actually 10-nanometer.
Each Bonanza Mine ASIC has 258 mining engines, and each engine computes parallel double SHA256 hashes. These engines occupy 90% of the die area and operate at an “ultra-low” voltage of 355 mV. The ASICs operate at 1.35 to 1.6 GHz at 75°C, consuming an average of 7.5 watts each at up to 137 GH/s.
A system of 300 chips delivers up to 40 TH/s at 3600W. For comparison, the Bitmain Antmienr S19j Pro 104T delivers 104 TH/s at 3068W, while the latest S19j XP model delivers 140 TH/s at 3010W. But it is worth remembering that the above applies to the first generation of Intel ASICs, and the company is already supplying the second.
The GeForce RTX 5090 will not repeat the fate of the fire-hazardous RTX 4090. Tests of the 12V-2×6 power connector showed that it works even when connected incompletely
Back in July, we learned that Nvidia was working on a replacement for the fire-hazardous 12VHPWR connector. And now the first tests of the 12V-2×6 connector have appeared on the Internet, which should replace the 12VHPWR.
The authors of the HardwareBusters channel visited the laboratory of Linewell, which produces power cables, including for video card manufacturers.
Linewell tested the cable with the new connector, and tested it in a format that simulated the most common cause of 12VHPWR melting. At first, Linewell specialists tested it in normal mode for almost an hour, and the connector only heated up to 46.5 degrees. Then the cable was not connected completely, which usually leads to melting, and a power of more than 640 W was applied to it, that is, exceeding the established limit of 600 W. The connector passed the test, heating up to only 41 degrees.
Intel wants a “five-year plan” in a year? Next year the company will have three lines of desktop processors at once, as Meteor Lake-S will still be released
Intel seems to have decided to exceed the plan not only in terms of technical processes, but also in terms of CPU lines. It turns out that Meteor Lake-S desktop processors will still be released.
Michelle Johnston Holthaus, Intel executive vice president and general manager of the client computing group, spoke about this. The PC World journalist, apparently not expecting an affirmative answer to his question regarding the fate of Meteor Lake-S, even asked again, and again received an affirmative answer.
So, tabletop Meteor Lake will still be released, and will be released next year. But now it’s not very clear how Intel is going to launch three lines at once within one year. Let us remind you that Raptor Lake Refresh will be released in October, and Arrow Lake is also expected next year. And if previously it was believed that the latter would simply replace the former, now another line is being added to them.
Perhaps Meteor Lake and Arrow Lake will coexist in the same way as in the mobile segment: Intel said that the former will occupy the mid-price segment, and the latter will be available in the upper price segment. And if these lines are released on desktop at the end of 2024, then they will together replace Raptor Lake Refresh. However, such a division will still be unusual, and Intel itself promised to release ARROW Lake much earlier than at the end of next year.
The Huawei Kirin 9000s platform is truly unique. It has a 12-core processor, although it’s far from record-breaking performance.
The Kirin 9000s platform continues to bring surprises, although smartphones based on it have been on sale for some time.
After the latest Huawei flagships received HarmonyOS 188.8.131.52, Geekbench software began to define the characteristics of the new SoC differently. If earlier it was seen as an eight-core solution, now the number of processor cores is indicated as 12.
It’s worth remembering here that AnTuTu initially determined that the platform had exactly 12 cores, however, including two Cortex-A34.
Geekbench, well, indicates the types of cores, but talks about three clusters: four cores with a frequency of 1.53 GHz, two with a frequency of 2.62 GHz and six with a frequency of 2.15 GHz. This information is confirmed by screenshots from the mobile version of the benchmark.
We have not yet seen mobile SoCs with 12-core CPUs. At the same time, the performance of the Kirin 9000s, despite this configuration, is far from flagship by 2023 standards, that is, the cores themselves are not the most powerful.
