Intel Core Ultra 5 235U vs Intel Core 5 210H

Intel Core Ultra 5 235U

The Intel Core Ultra 5 235U is an upper mid-range CPU with 12 cores from the Meteor Lake U series, which was introduced at the beginning of 2025. The chip is similar to the Meteor Lake U series, but the compute part is manufactured in the modern Intel 3 process and therefore offers higher clock rates.

The chip continues to rely on a tile/chiplet design. The smaller compute tile (compared to the H processors) offers 2 performance cores (P cores, Redwood Cove architecture, SMT) and 8 efficiency cores (E cores, Crestmont architecture). The P-cores support hyperthreading (therefore 14 threads together) and clock up to 4.9 GHz. The E-cores clock at a maximum of 4.1 GHz. In addition, there are now two more low-power efficiency cores with up to 2.4 GHz on the low-power island; the compute tile can therefore be completely deactivated when idle and during simple tasks in order to save power.

Performance

Due to the higher clock rates and the support of faster memory, the performance is slightly above the old top model Core Ultra 5 165U (12 cores, max 4.9 / 3.8 GHz, 12 MB cache).

Graphics unit

The Core Ultra 5 135U offers a new Arc-based iGPU called Intel Graphics with 4 Xe cores and 64 EUs that reach a maximum of 2.05 GHz. However, the performance is far below the new Arc iGPU in the H series.

Features

Arrow Lake-U has integrated WiFi 6E (WiFi 7 optional). The integrated memory controller now supports LPDDR5/x-8400 or DDR5-6400 (max. 128 GB). A dedicated NPU (2x Gen3 Neural Compute Engines) is now used. The Xe Media Engine supports MPEG-2, AVC, VC-1 Decode, JPEG, VP8 Decode, VP9, HEVC and AV1 Decode up to 8K 10-bit HDR. The chip now supports PCIe-5.0 (x8 for GPU) and PCIe-4.0 (three x12 for SSDs).

Power consumption

The Intel Core Ultra 5 135U is specified with 15 watts TDP (base) and 57 watts (PL2) max. turbo power. Meteor Lake consists of five individual chips, whereby the processor part is manufactured in the new Intel 3 process (5nm). The graphics unit is produced at TSMC in N5 and the SoC and I/O tile in the older N6 process. These 4 chips are then applied to the 22nm base tile using the Foveros process.

Intel Core 5 210H

The Intel Core 5 210H is a mid-range mobile CPU for laptops of the Raptor Lake-H series (Alder Lake architecture). It was announced in late 2024 and offers 4 of the 6 performance cores possible (P-cores, Golden Cove architecture) and 4 of the 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading making for 12 processing threads when combined with the E-cores. The clock rates range from 2.2 to 4.8 GHz (single core boost) on the performance cluster and 1.6 to 3.6 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (comparable to the Core i7-6700HQ). All cores have access to the 12 MB L3 cache.

Compared to the old Core i5-13420H, the Core 5 210H offers slightly higher clock speeds (e.g. boost core speeds + 200 MHz).

Performance

Thanks to the higher clock speeds, the Core 5 210H can surpass the old Core i5-13420H, especially in single threaded workloads.

Features

The integrated memory controller supports various memory types up to DDR5-5200 (up from DDR5-4800 of the i5-12500H). The Thread Director (in hardware) can help the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. The CPU now supports PCIe 5.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.

The integrated graphics adapter is based on the Xe architecture and offers 48 of the 96 EUs (Execution Units) possible.

The CPU is rated at 45 W base power (115 W PL2) but most laptops will use a PL1 of around 60 Watt. The SoC is manufactured on an improved 10nm process at Intel, which is known as Intel 7.
