Review It's a tough time to be a PC enthusiast. Between the memory crunch and the AI boom driving up prices on storage, DDR5, and GPUs, it's gotten prohibitively expensive to build a PC.
Amid this turmoil, Intel hopes to win some goodwill from budget-conscious customers with its newly announced [1]Core Ultra 200S Plus family of desktop processors.
The new chips boast higher core counts, more aggressive frequency curves, and, more importantly, are launching at much lower prices this time around. At $199 and $299 respectively, Intel's all-new Ultra 5 250K and Ultra 7 270K reflect a level of market awareness that we haven't seen from Chipzilla in quite a while.

Intel's Arrow Lake refresh is its most compelling value proposition in years. And, while the chips can't contend with AMD's cache-stacked X3D parts in gaming, they're significantly cheaper while also delivering strong performance in production workloads thanks to all those extra efficiency cores.

[4]
In this review, we'll be digging into the good, bad, and the ugly of Intel's latest generation of desktop CPUs covering everything from office productivity to HPC, and yes, gaming.
But first let's take a closer look at Intel's latest chips.
The chips
The overarching theme for Intel's Arrow Lake refresh is more cores per dollar. Both Core Ultra 5 and Ultra 7 Plus processors gain four additional efficiency (E-cores) over last gen.
With 24 cores (8-P and 16-E cores), this puts the 270K in direct contention with Intel's 285K. The new Ultra 7 doesn't clock as high, with a max turbo 200 MHz slower than the flagship. But, for many, those lower clocks are more than worth the lower MSRP.
[5]
The new Core Ultra 5 250K enjoys similar gains. The chip now boasts 6-P cores and 12-E cores for a total of 18 cores and 18 threads. Remember that there's no hyperthreading (SMT) this generation. At least as far as core count goes, the part is essentially a Core Ultra 7 265K that's had two of its P-cores fused off and its frequency tables remapped.

Apart from the higher core count, the parts don't look all that different from their pre-refresh siblings, but the architectural improvements actually go deeper than the speeds and feeds might suggest.
Intel has tweaked its boost algorithm so that, under sustained all-core loads, the chips can now maintain higher clocks overall. When all six of its P-cores are loaded up, the 250K can now maintain a 5.1 GHz core clock, up 100 MHz from the prior gen. Meanwhile, the 270K's E-cores now clock 100 MHz faster, while the all-P-core boost table has been updated to more closely resemble the 285K at 5.4 GHz, up from 5.2 GHz on the 265K.
Alongside the reworked boost tables, Intel bumped the die-to-die fabric frequency by 900 MHz. Arrow Lake saw Intel bring its chiplet – or, as Intel prefers, tile – based design philosophy to the desktop for the first time.

Not much has changed here. As we understand it, the tiles are still fabbed by TSMC and packaged in-house using Intel's Foveros 3D packaging tech. However, this means that Arrow Lake's memory controller is on a different tile than its P or E-cores. By increasing the fabric bandwidth, Intel aims to drive down memory latency, improving overall performance in the process.
On the topic of memory, Intel's Arrow Lake refresh natively supports DDR5 JEDEC speeds up to 7,200 MT/s, with 8,000 MT/s memory officially sanctioned via XMP profiles. That's a substantial uplift over Intel's original crop of Arrow Lake processors which officially topped out at 6,400 MT/s, though higher memory speeds were possible by overclocking.
And if you've got exceedingly deep pockets, Intel has also added support for 4-rank memory modules up to 128 GB each. We don't imagine many folks will actually take advantage of this capability, as just one of those DIMMs will almost certainly retail for several times the cost of a 270K.
[7]
According to Intel, these enhancements give the parts a whopping 83-103 percent multi-threaded performance advantage over AMD's entry-level 9600X and mid-tier 9700X processors, at least in rendering and synthetic benchmarks. It's easy to make comparisons like this when you slash the price of your products to undercut the competition.
The 270K's higher core count doesn't help nearly as much in gaming, with Intel claiming a four percent advantage in average FPS over the Ryzen 7 9700X. Meanwhile, Intel only asserts that its $199 250K ties AMD's 9600X across its suite of games.
BOT and the chipset driver
While some of the 200S Plus series' performance uplift comes from architectural refinements, much of the chip's gaming performance can be attributed to software enhancements.
Intel has a new Platform Performance Package, which bundles up all the libraries, performance profiling, power management, and application optimizations into a single installer to make getting up and running less of a headache.
Binary Optimization Tool Supported Titles
Assassin's Creed Mirage
Borderlands 3
Cyberpunk 2077
FarCry 6
Final Fantasy XIV: Dawntrail
Hitman 3
Hogwarts Legacy
Marvel's Spider-Man Remastered
Naraka: Bladepoint

Alongside the installer is what Intel is calling its Binary Optimization Tool (BOT), which leverages its compiler and profiler tech to reduce execution overheads and boost instructions per cycle for supported x86 binaries at runtime.
On average, Intel says BOT delivers an 8 percent uplift in gaming with some titles showing FPS gains of more than 22 percent.
BOT works by using the chipmaker's hardware and software profilers to analyze pre-compiled binaries for sources of cache misses, front-end stalls, and mis-predictions, and other hiccups that kill performance at runtime. This information is then used to develop alternative binaries optimized for Intel hardware which are then shipped as part of the Platform Performance Package.
"We don't see source code. We don't change source code. We do not reverse engineer. We do not recompile. Everything that the workload was originally designed to do stays in the binary," Robert Hallock, VP of Intel's enthusiast channel biz tells us. "It's akin to shader replacement for a graphics card. You've got a much faster, more optimized shader for that graphics pipeline, we're doing the same thing on a CPU."
Because of this, support is limited to select games at launch, and users will need to manually toggle it on in the Intel Application Optimization utility. Intel is also being intentionally cautious so as not to accidentally trigger anti-cheat software, which means it's not yet available for online titles.

Binary Optimization Tool vs Signed Binaries
Anonymous Coward
Can someone explain how this tool is supposed to work when an OS expects a signed binary? Any change to the binary is supposed to be blocked, right?
Another problem with enforced signing, but let's be real: how many users know enough to turn off enforced signing to run an optimized binary?
And why does the BOT only target games? If Intel wants buzz, it needs to target Firefox and Chrome.
Re: Binary Optimization Tool vs Signed Binaries
Brewster's Angle Grinder
Presumably they are signed by Intel?
And Firefox and Chrome are moving targets. (But they are probably better optimised anyway.)
Re: Binary Optimization Tool vs Signed Binaries
Anonymous Coward
> Presumably they are signed by Intel?
Article makes it seem like a deployed product ("alongside the installer..."). Real shame if Intel is the gatekeeper, signing on the backend and only shipping a downloader. That'd be quite different than a public beta where it only works with supported binaries for now.
> And Firefox and Chrome are moving targets. (But they are probably better optimised anyway.)
I wonder if they've even tried. Meaningfully optimized browsers would be a big deal for everyone, and a deciding factor for many orgs/users.
More cores, higher clocks, and lower prices? What's not to like?

Intel? I have bought AMD processors ever since Intel's blatantly illegal attempts to cut off the oxygen on AMD processors by offering "special" consideration/compensation ($) to PC manufacturers to use only Intel processors. It was until very recently difficult to find top of the line AMD laptops especially from major manufacturers. Luckily for AMD Intel's numerous missteps over the last several years gave them a crack in the wall that they took full advantage of. Intel somehow still rules the roost but the are seriously straining their necks looking over their shoulder. And just to be clear, I do not want Intel to fail, I just want them to compete fairly with their competition. At this point it looks like they have no other choice which is good for everybody.

One major advantage AMD has pretty much always had is that they don't obsolete their CPU sockets anywhere near as often as Intel. That is AMD's sockets are good for 6-8 years generally, while Intel drops theirs after about 2 years.

Anything greater than quad core is overkill for my needs. A quad core in the 3.7 to 4.0 Ghz range would run all my software, games too.
The PC market is in the midst of an AI-fueled price crunch. Memory and storage can easily cost more than a CPU, and enthusiasts are having to make tough decisions on where to allocate their budgets.
And not forgetting the obscene cost of GPUs at the moment.
I spent all my money on a gaming PC icon -->
