It's part of Jim Keller's Royal Core Family of CPU's that he helped architect for his short stint in Intel. Even if they kept it under NDA, I think rumors would've been swirling by now.MLiD already leaked what Intel is going to try to replace Hyper-Threading with. It has big software implications, and Intel would have publicized that info further in advance of such products launching. I think there's pretty much no chance of that tech making it into Arrow Lake, however. That sounds exactly like what Soft Machines was working on. It's hard to see why you'd need hyperthreading on the P-cores, when you have so many E-cores that are each faster than a second thread on a P-core. Long ago, there were rumors of them going to 32 E-cores. However, they'd probably want to boost E-core count, at the same time. Even if they kept it under NDA, I think rumors would've been swirling by now.īit_user said:In mainstream CPUs, I could see ditching hyperthreading. Intel bought them, so presumably they are still working away on the technology. There have long been rumors that Intel will move to a new approach with its P-Cores that discards hyperthreading, which allows two threads to run on a single CPU core, for a new approach that it has outlined in a patent.That sounds exactly like what Soft Machines was working on. In server CPUs, they lose enough margin by disabling hyperthreading that I think they probably wouldn't want to cede that ground to AMD or ARM.

Evidence of chloroplast capture in south American Nothofagus (subgenus Nothofagus, Nothofagaceae). Schima plastid genome recently diverged standard barcodes super-barcodes.Īcosta, M. We therefore call for developing multilocus nuclear markers for species discrimination in plant groups. Taken together, our study suggests that by no means are super-barcodes immune to the challenges imposed by evolutionary complexity. For Schima and other taxa with similarly recently divergence and low levels of genetic variation, incomplete lineage sorting, hybridization or taxonomic oversplitting are all possible causes of the failure. No samples were correctly assigned to species using standard DNA barcodes and nrDNA arrays, while only 27.27% of species with multiple accessions were distinguished using the plastid genome and its partitioned data sets-the lowest estimated rate of super-barcode success in the literature so far. In this study, we generated multiple data sets comprising standard DNA barcodes (matK, rbcL, trnH-psbA, nrITS) and super-barcodes (plastid genome, nrDNA arrays) across 58 individuals from 12 out of 13 species of Schima from China. Morphological homoplasy among Schima species makes the genus a model for testing the efficacy of super-barcodes. Plastid genome and nuclear ribosomal DNA (nrDNA) arrays, proposed recently as "super-barcodes," might provide additional discriminatory power and overcome the limitations of traditional barcoding loci, yet super-barcodes need to be tested for their effectiveness in more plant groups.
