Intel Core i3-1315U Review

Intel Core i3-1315U laptop processor: 6 cores (2P + 4E), 8 threads, up to 4.5 GHz, 10 MB cache, Intel UHD Graphics (64 EU, up to 1.25 GHz), 15 W base power, 55 W max turbo, Intel 7, 13th Gen Raptor Lake.

The Intel Core i3-1315U is a 6-core, 8-thread laptop processor from Intel's 13th Gen Raptor Lake-U family, launched in early 2023. It boosts up to 4.5 GHz, has 10 MB of cache and Intel UHD Graphics with 64 execution units, all in a 15 W base power envelope. You'll find it in entry-level thin-and-light, student and business laptops, not as a boxed chip.

What the Core i3-1315U is

The Core i3-1315U is an entry-level 13th Gen laptop chip, soldered to the motherboard, so you pick it by picking the laptop. It has 2 performance cores and 4 efficient cores, 8 threads in total, with the performance cores boosting to 4.5 GHz and the efficient cores to 3.3 GHz. It shares 10 MB of cache, runs at a 15 W base power with up to 55 W in short bursts, and is built on Intel 7. It supports up to 96 GB of DDR5-5200, DDR4-3200, LPDDR5/x-5200 or LPDDR4x-4267 memory in two channels, plus Thunderbolt 4 and PCIe Gen 4.

Performance in everyday use

The two performance cores boost as high as those in many Core i5 U-series chips, so light tasks such as browsing, email, documents and video calls feel responsive. With only 4 efficient cores instead of 8, it falls further behind when many things run at once or during long multi-core jobs such as video exports. Laptop makers set their own power limits and cooling, so thin budget models may run it slower under sustained load.

Graphics

The integrated Intel UHD Graphics have 64 execution units running at up to 1.25 GHz, fewer than the 80 found in Core i5 U-series chips. They handle 4K video playback, up to four displays and basic photo editing, but gaming is limited to very light or older titles at low settings. Dual-channel memory still helps. There is no NPU for AI features.

Comparison to Alternatives

Against the 12th Gen Core i3-1215U it replaces, the i3-1315U keeps the same 2P + 4E layout with a higher boost clock and support for faster memory. The 2024 Core 3 100U is the same class of chip under Intel's newer naming. AMD's Ryzen 3 7330U and Ryzen 3 7320U are its direct budget rivals with 4 cores and 8 threads each. Stepping up to a Core i5-1334U adds 4 more efficient cores and stronger graphics. The comparison pages below show each spec side by side.

Should you buy a laptop with it?

Yes, if you need a low-cost laptop for school, documents, browsing and video calls. Look for at least 8 GB, ideally 16 GB, of dual-channel memory and an SSD, since those matter more at this price than the processor. If you multitask heavily, edit video or want any gaming, a Core i5 or Ryzen 5 laptop is worth the extra money.

Our verdict

FAQs

Is the Intel Core i3-1315U good for a laptop?

Yes, for basic everyday use. It handles browsing, documents, email, streaming and video calls well. It is not meant for heavy multitasking, video editing or modern games.

Is the Core i3-1315U a desktop or laptop processor?

It is a laptop processor. It is soldered to the laptop motherboard and is not sold as a boxed CPU, so you cannot buy it on its own or swap it later.

What is the difference between the Core i3-1315U and the i5-1334U?

The i3-1315U has 6 cores (2 performance, 4 efficient) and 8 threads with 10 MB of cache and Intel UHD Graphics. The i5-1334U has 10 cores (2 performance, 8 efficient), 12 threads, 12 MB of cache and graphics with more execution units. The i5 is the better pick for multitasking and light gaming.

Does the Core i3-1315U have Iris Xe graphics?

No. It uses Intel UHD Graphics with 64 execution units, a smaller graphics unit than the 80 execution unit graphics in Core i5 U-series chips.

Can the Core i3-1315U play games?

Only very light or older games at low settings. For anything more demanding, choose a laptop with a Core i5, a Ryzen with stronger Radeon graphics, or a dedicated GPU.
