I mean guys if you have no economics basis and your jobs do not involve finance perhaps you should not comment :) Consumer excited by their masters charging more, imagine if Intel or Nvidia or ATI, or S3 or any tech company charged £50 more each generation, a CPU or GPU or Monitor would cost you ehmmm £50k circa if we start from 8086 onwards. It must be sad being a fanboys of a brand making silicon chip.like really sad. They are both corporates, sorry I hope it won't come as a shook to you :) It also humorous how fanboys cried at Intel "robbing" "price gauging" but now that their master AMD is showing to be as anti consumer, even more so with GPU fanboys defend what they were crying about before. I can't wait to see how intel counter punches here. Even AMD and Nvidia is getting interesting! A fantastic time to be a home builder. ![]() And it's been a bit since I shopped intel chips, but last I checked, Intel hasn't been bundling coolers with their chips for a while? Someone who follows intel might be able to provide me some guidance there.Īs a home building enthusiast (for the last decade or so) this is a very exciting time having legit competition between team red and team blue. For the last decade, Intels flagship processor has been half again as much as the current Ryzen5000 and so few tech sites batted an eye about it. VTXcnME said:Humorous the 'cons' that list price increases of $50. The reduced traffic on the Infinity Fabric also contributes (it always requires more energy to move data than to process it). Naturally, performance and power efficiency will improve as a function of architectural improvements. Notably, AMD also added support for memory protection keys, added AVX2 support for VAES/VPCLMULQD instructions, and made a just-in-time update to the Zen 3 microarchitecture to provide in-silicon mitigation for the Spectre vulnerability. +4 table walkers in the Translation Look-aside Buffer (TLB).More flexibility in load/store operations.Overall higher bandwidth to feed larger/faster execution resources.Major Design Goal: Larger structures and better prefetching - enhance execution engine bandwidth.Floating point FMAC is now one cycle faster.Floating point has increased bandwidth by +2 for a total of 6-wide dispatch and issue.Reduced latency for select float and integer operations.New dedicated branch and st-pickers for integer, now at 10 issues per cycle (+3 vs.Major Design Goal: Reduce latency and enlarge to extract higher instruction-level parallelism (ILP).Finer granularity in switching of op-cache pipes."No Bubble" prediction to make back-to-back predictions faster and better handle branchy code.L1 branch target buffer (BTB) doubled to 1024 entries for better prediction latency.Major Design Goal: Faster fetching, especially for branchy and large-footprint code.Here's AMD's high-level bullet point list of improvements to the Zen 3 microarchitecture: However, the larger 元 cache does come with an increase in 元 latency to the tune of seven additional cycles. This new design will tremendously benefit latency-sensitive applications, like games - particularly if they have a dominant thread that accesses cache heavily (which is common). Additionally, lower cache latency can reduce the amount of time a core communicates with the 元 cache. ![]() A larger pool of cache resources keeps more data closer to the cores, thus requiring fewer high-latency accesses to the main memory. These enhancements are important because games rely heavily on the memory subsystem, both on-die cache and main memory (DDR4). All of these factors will result in faster transfers (i.e., lower latency) communication between the two eight-core chiplets, and it possibly removes some of the overhead on the I/O die, too. This results in less contention on the fabric, thus simplifying scheduling and routing, and it could also increase the amount of available bandwidth for this type of traffic. Still, because an entire layer of external communication between the two four-core clusters inside each chiplet has been removed (as seen in the center of the chart above), the Infinity Fabric will naturally have far less traffic. ![]()
