Tech News:
A rapid rise
Ever since AMD launched the Zen architecture just over three years ago, it has progressed at a relentless pace. At the time, Intel’s $1,100 8-core i7-6900 seemed like it had all the cores you’d ever need. However, AMD moved the goalposts, unveiling the 8-core Ryzen 7 1800 at a much lower $499 price point. That was followed a little later by the $999 Threadripper 1950X with no fewer than 16 cores.
Intel had already unveiled the 18-core i9-7980XE, but it cost double the price at $1,999. Yes, it had a significant speed edge over the Threadripper 1950X, but AMD was starting to close the gap for multi-threaded workstation CPUs — a key and very profitable market for Intel.
AMD quickly changed the game again with its Zen 1 (second generation) Ryzen and Threadripper CPUs. When it first shipped, the 32-core $1,799 Threadripper 2990X was nearly on par with Intel’s best workstation chips, including the $3,000 28-core Xeon W-3175X.
Several months later, Intel launched the $2,000 i9-9980XE. It was still a better option for clock-speed sensitive tasks like Adobe Creative Suite and gaming than AMD’s Threadripper or Ryzen 7 chips, thanks to its stronger per-core performance and better memory architecture. However, the 2990WX could hold its own for multithreaded rendering, thanks to the sheer number of cores, and took the lead in tile-based rendering scenarios like Blender.
When AMD announced the 16-core, Ryzen 9 3950X for just $750, it had good reason to be confident. Some pretty huge architectural improvements and increased clock speeds made performance significantly stronger than the Core i9-9980XE, but at nearly a third of the price. To counter, Intel launched the 18-core Core i9-10980XE and cut the price by half, down to $1,000 — something it wouldn’t have likely done without the competition — but it still wasn’t enough.
AMD has replied again with the 24- and 32-core Threadripper 3960X and 3970X CPUs, priced at $1,399 and $1,999, respectively. According to reviews, those chips are competitive with the i9-10980XE for clock speed-sensitive tasks, but they’re now handily winning when it comes to multi-threaded workstation rendering performance, albeit it at a significantly higher price point.
In a short time, AMD has progressed from eight to 32 cores and moved from a 14-nanometer process down to 7-nanometers, while making big architectural improvements to cut the gap in IPC, or instructions per clock. It has also refined its manufacturing technique for “chiplets,” which are a very efficient way to build multi-core CPUs. Meanwhile, Intel is still stuck on a refined 14-nanometer++ process for its key gaming and workstation parts and has scrambled to stay competitive in the multi-core segment.
AMD takes over workstations
AMD’s new Threadripper chips pose a huge problem for Intel. Yes, they’re more expensive than the consumer-oriented Core i9-10980XE, but Intel now has nothing to counter them in the HEDT market. The closest chip it has is the 28-core Xeon W-3275M, but it costs nearly quadruple the price, at $7,453. (Last year’s $3,000 28-core W-3175X is far behind AMD’s 3970X chip in performance.)
Another huge plus for AMD is the new TRX40 platform for its latest HEDT chips. While it doesn’t let you drop the new Threadripper chips into old Zen 1 motherboards, the new architecture has some big advantages for creators. Mainly, it introduces PCIe 4.0 support, delivering much higher SSD speeds for 4K and 8K video editors. The new motherboards also have more PCIe slots, ECC RAM (256GB) and USB 3.0 ports.
In terms of performance, the Threadripper 3960X and 3970X chips trounce the Core i9-10980XE in every single workstation benchmark, even in single-threaded mode. So while the chips are more expensive, the rendering performance per dollar is considerably higher.
That equation will likely shift even more in AMD’s favor when the Threadripper 3990X comes out in 2020, as that chip should cost even less per core. That will help 3D animation and post-production facilities reduce costs as they’ll be able to get more rendering performance out of a single workstation or render node.
Intel’s still winning in gaming and mainstream computing (for now)
Intel’s primary gaming CPUs, like the i9-9900K and i9-9900KS, outperform AMD’s Ryzen 9 3950X by a comfortable margin — and cost less to boot. However, the consumer-focused Ryzen 3600 and 3700 cost less than the 9900K and are considered better picks than Intel’s i7 and i5 offerings.
Virtually every desirable high-end laptop out there packs Intel Core i9 or i7 chips, along with NVIDIA’s GTX or RTX graphics cards. Why is that? Intel still has the edge in overall clock speeds, though AMD has reduced the gap over the last generation. At the same time, AMD seems determined to make its chips appeal to both workstation and gaming users, offering gaming-oriented chips like the 3700 with higher thread counts than competing Intel products. (At the same time, gaming performance depends much more on the GPU than the CPU, so slight differences in CPU performance aren’t that important.)
And when it comes to laptops, Intel simply dominates, with a huge portfolio of eight-, ninth- and 10th-gen CPUS, all of which have built in GPUs. It’s a lot of work for a manufacturer to switch from Intel to AMD — you can’t simply swap out a CPU as the chipset and other motherboard architecture needs to change with it. Advanced IO like Thunderbolt has also been a key differentiator for Intel; although, USB4 changes that. As it can’t really compete, AMD has seemingly avoided the high-performance segment. Its laptop chips simply have poor performance per watt next to Intel, and few AMD CPUs have integrated graphics. That could change, though, with its Zen 3 7-nanometer+ architecture. It doesn’t seem like AMD would have much trouble crashing this segment, too, if it wanted to.
Intel also owns the mainstream laptop market, particularly in the 15- to 25-watt CPU segment, where you’d find machines like the 13-inch MacBook Pro. Again, it’s hard for AMD to compete with the sheer number of parts Intel has across its eight-, ninth- and 10th-gen mobile platforms. Cracking the laptop market seems more like a question of will rather than a lack of technological prowess from AMD. For now, it might feel it’s better off focusing on the more profitable high-end segment.
What’s to come
When Intel finally releases full-fledged, 10-nanometer gaming chips, it will no doubt change the equation against AMD. From what we’ve seen so far, they’ll deliver modest performance gains of around 10 percent, while sipping less power.
That should be enough to keep it ahead in the mainstream segment it already dominates — and possibly in gaming (depending on what AMD does). What about for workstations? At this point, it seems unlikely that Intel will be able to best AMD in the all-important performance-per-dollar category, unless it really pulls off something incredible.
AMD, meanwhile, says that its Zen 3 process is ready and will first appear on its Epyc server CPUs. It has promised an “entirely new” architecture based on a 7 nanometer+ manufacturing process. That could deliver performance gains in the neighborhood of 15 percent, with correspondingly lower power draws. At the same time, AMD will continue increasing core counts, memory bandwidth and I/O connectivity.
What’s also interesting is that AMD has promised to continue its current “tick-tock” design cycle. That means it will shrink the chip size down on the “tick” cycle, while changing the architecture on the “tock.” Intel aband
