Intel Core Ultra 9 285K Tops PassMark Single-Thread Benchmark
According to the latest PassMark benchmarks, the Intel Core Ultra 9 285K is the highest-performing single-thread CPU. The benchmark king title comes as PassMark's official account on X shared single-threaded performance number, with the upcoming Arrow Lake-S flagship SKU, Intel Core Ultra 9 285K, scoring 5,268 points in single-core results. This is fantastic news for gamers, as games mostly care about single-core performance. This CPU, having 8 P-cores and 16 E-cores, boasts 5.7 GHz P-core boost and 4.6 GHz E-core boost frequencies. The single-core tests put the new SKU at 11% lead compared to the previous-generation Intel Core i9-14900K processor.
However, the multithreaded cases are running more slowly. The PassMark multithreaded results put Intel Core Ultra 9 285K at 46,872 points, which is about 22% slower than the last-generation top SKU. While this may be a disappointment for some, it is partially expected, given that Arrow Lake stops the multithreaded designs in Intel CPU families. From now on, every CPU will be a combination of P and E-Cores, tuned for efficiency or performance depending on the use case. It is also possible that the CPU used inn PassMark's testing was an engineering sample, so until official launch, we have no concrete information about its definitive performance comparison.

So Arrow lake is the first Intel CPU to abandon hyperthreading/SMT on P-cores? (E-cores already lack HT)
The currrent architecture has to juggle HT cores, e cores and P cores, and AFAIK that's not very efficient/overly complex. Disabling HT also generally lowers latency.
But it comes with area cost due to needing more logic and registers, duplicated logic and registers for some structures while partitioning others. As you can have things like Reorder Buffers which might be statically partitioned to each thread(say 256 in total split in two 128 entry ones) or competitively shared(each thread uses as much as it needs - but more logic is needed to implement that). In essence, HT/SMT implementations can vary in perfomance and a lot of attributes.
You generally do get more out of it though.
I believe that Intel has kinda abandoned it in their consumer chips more due to scheduler. Thinking on stuff like Intel Application Optimization, it seems like there is quite a bit of performance on the table from a number of applications not being scheduled properly. This is even worse in cases like Meteor Lake where you have 4 types of cores, the normal P-core core, the HT core, the E-core and the LP E-core.
Because from a pure performance perspective, it does not seem like designing without HT had any benefit to Lion Cove, except maybe(and not even sure about that) for mobile.

Intel still domiates the relationships with OEMs, still keeps AMD out of the premium laptop models, etc.....Intel is still very much the dominant party in this duopoly, and in fact, it would be better for consumers in general if they lost more marketshare to AMD (based on the belief that an even 50/50 split in marketshare would be the beat for consumers).
I'm more interested in Arrow Lake Refresh gain or next gen.
This is just rehashed, canceled Meteor Lake Refresh. Nothing to see here.There is a rumor that such CPUs will be released next year, Bartlett Lake, rumor does not mention if they will be for Desktop though.
Be interesting to see how MT plays out, 8+16 small vs AMD's 9950X 16 large/32T, and of course the 9000 series x3D will bring AMD to parity or there abouts with Arrow Lake in gaming as has been the case with the last 2 gens, so pretty much same old all round, I am going to hold to my trusty old 5700x and RX 6800 for a couple more years by the looks of it as there is no compelling reason to spend £600-700 for a platform upgrade, not withstanding GPU for negligible performance increase, I guess we have had it good for the last few gens barring GPU prices going through the roof, another reason I'll be sticking with what I have until I can get a meaningful performance uplift (1.5-2x) from my 6800 for <£300 :rolleyes:
Now wecan't know where it is anymore ;p
As you can see in the link posted by AnotherReader, the execution units have been split across more execution ports, which allows for higher peak throughput, but also requires more scheduling for the front-end. I think these changes, along with the removed constraints from dropping HT will pay off a couple of generations down the road. But also this would make it easier for Intel to add even more execution units to high-end workstation and sever parts, even more than they currently do. (Who wouldn't like workstation parts with more FPUs etc at the cost of a few hundred MHz peak boost?)It's called Xeon W.
Heck, Qualcomm might even buy Intel just to use Intel products as space heaters in ARM team developer cubicles during cold San Diego winters.
