Intel’s Core i5 and Core i7 CPUs are some of the most classically popular Intel processors, but that naming convention was retired with its Meteor Lake CPUs in 2023, replaced with a new Core Ultra branding. Now, with Intel’s latest 200-series Arrow Lake processors, they’re known as Core Ultra 5 and Core Ultra 7. There isn’t a huge change in what you can expect from the various models within each tier, but Core Ultra is the new naming convention.
We’re here to break down all the differences between Intel’s Core Ultra 5 and Core Ultra CPUs, both on desktop and mobile. They’re closer than they were in previous years, but still have some very real reasons to pick one over the other.
Core Ultra 5 vs Core Ultra 7: what’s the difference?
Like Core i5 and Core i7 CPUs that came before, Core Ultra 5 and Core Ultra 7 represent different portions of Intel’s CPU stack. Where Core Ultra 3 represents entry-level processors, and Core Ultra 9 the flagship chips, Core Ultra 5 and Core Ultra 7 represent the more mid-range options. These have traditionally been super popular among gamers, although the limited gaming performance improvements of the Core Ultra 200 generation somewhat buck that trend.
Still, if you’re building a new PC for work or want to work and play on the same machine and are keen on Intel, the Core Ultra 5 and Core Ultra 7 chips are some of the best processors for most people.
As it stands, the Core Ultra 5 range includes the 225, 235, 245, and 245K. There are also F variants of some of them, which don’t have onboard graphics. The K-variant is overclockable and has higher clock speeds. All of them have six performance cores, and up to eight efficiency cores (the 225 has just four E cores).
The Core Ultra 7 range includes the 265 and 265K, as well as F variants without graphics. What separates these from the Core Utlra 5 models, is that each of them has eight performance cores and 12 efficiency cores. They also have higher clock speeds and more cache. They’re more expensive across the board, too.
Should you buy a Core Ultra 5 or a Core Ultra 7?
The Core Ultra 5 processors sit in a sweet spot of price versus performance. For most users, a Core Ultra 5 processor is more than enough to handle day-to-day tasks, and they can even hold their own when it comes to gaming – although AMD’s CPUs currently hold a commanding lead on peak gaming performance. The most recent Core Ultra 5 chips under the Arrow Lake series, top out at 14-cores in total.
Core Ultra 7 CPUs offer better performance thanks to their mix of more cores (particularly the additional two performance cores) and higher clock speeds. This is particularly noticeable in games that can take advantage of the additional cores, and in demanding applications, like those used for photo and video editing.
If you want to play games, browse the internet, and dip your toes into applications like Premiere or Photoshop, you can definitely achieve all of that using a Core Ultra 5, but a Core Ultra 7 CPU will give you a more effective tool for work and play.
Intel Core Ultra 5 vs. Core Ultra 7 on desktop
Intel has a range of Core Ultra 5 and Core Ultra 7 CPUs on desktop, all of which are worth considering if you’re looking to build a new PC for gaming or more professional tasks.
| Cores/Threads | Boost clock (P/E) | L2+L3 Cache | TDP (Base/Turbo) | |
| Core Ultra 7 265K | 20 (8P+12E) | 5.5GHz/4.6GHz | 66MB | 125W/250W |
| Core Ultra 7 265 | 20 (8P+12E) | 5.2GHz/4.6GHz | 66MB | 65W/182W |
| Core Ultra 5 245K | 14(6P+8E) | 5.2GHz/4.5GHz | 50MB | 125W/159W |
| Core Ultra 5 245 | 14(6P+8E) | 5.1GHz/4.5GHz | 50MB | 65W/121W |
| Core Ultra 5 235 | 14(6P+8E) | 5.0GHz/4.4GHz | 50MB | 65W/121W |
| Core Ultra 5 225 | 10(6P+4E) | 4.9GHz/4.4GHz | 44MB | 65W/121W |
Note: Intel no longer supports simultaneous multithreading/hyperthreading, so its latest CPUs have the same number of cores and threads.
The main differentiating factors between the Core Ultra 5 and Core Ultra 7 CPUs on desktop are in clock speeds and core counts. The K variants stand apart for their higher clock speeds and power demands, but elsewhere the chips aren’t particularly distinct. There’s not a huge difference between the Core Ultra 5 245 and core Ultra 5 235, for example.

Older desktop CPUs like Intel’s 14th generation Core i5 14600K and Core i7 14700K are still relevant in older PCs and can offer strong performance, but if you’re building a new Intel PC in 2025 it’s better to opt for one of these new Core Ultra 200 models. Not only is performance and performance per watt improved, but they also have a strong upgrade path ahead of them, while older CPUs will require an entire motherboard and memory overhaul whenever you want to upgrade your CPU to something newer.
Intel Core Ultra 5 and Core Ultra 7 on laptops
Intel has a wider range of CPU options for laptops but they follow similar naming conventions to CPUs on desktops. Its main chips are the Core Ultra 7 265 and 255, and the Core Ultra 5 235 and 225. As with desktop the Core Ultra 7 models have more cores (up to 24 with a mix of performance, efficiency, and low power efficiency cores), and higher clock speeds.
However unlike desktops, Intel segments its laptop CPUs into HX, H, and U models. If a CPU has an HX after its name, those are the highest performing options designed for gaming and demanding applications. H models are not quite as fast, but are equally impressive and offer slightly better battery life. Arrow Lake U CPUs are the weakest of the bunch but offer the best performance per watt, helping to extend battery life and improve efficiency.
Although our general advice of buying higher-end Core Ultra 7 CPUs will tend to grant better performance, it’s not as cut and dry with laptops. So much depends on their design and thermal properties that you’re better off looking at individual reviews of laptop models to see whether they’re right for you.
There are also older Core Ultra 100 generation Meteor Lake processors still available in some Intel laptops. Those aren’t as fast or as efficient, but still represent viable options if you can find one at a good price. You’re usually better off buying newer laptops, though, as you’ll get the mix of the latest features and the best performance.
What about Core Ultra 9
Intel’s Core Ultra 5 and Core Ultra 7 CPUs, while potent, cater primarily to the mainstream consumer market. The higher-end Core Ultra 9 processors are geared more towards high-end gaming and extreme professional performance. They are the best CPUs Intel has and they’re priced accordingly.
While you might get a Core Ultra 5 CPU for a couple of hundred bucks, the Core Ultra 9 models are more like $600-700.
The 285K is currently the most powerful chip offered by Intel in the mobile space, packing 24 cores and a 5.7GHz boost clock. It wasn’t super impressive when we tested it and actually falls behind the last-generation 14900K in some games, but it’s still a powerhouse CPU and up there with some of the fastest in the world; Especially in professional workloads.
On laptops, the 285HX reins supreme, with 24 of its own cores and a 5.5GHz boost clock giving it a significant leg up over its brothers and sisters. As with Core Ultra 5 and Core Ultra 7 laptop CPUs, though, you need to read individual reviews to see if it’s worth it for you.
For most people, Core Ultra 9 isn’t necessary and your money is better spent elsewhere. If you want the best Intel has to offer, though, it’s the best there is.
