Intel Core i5-7500T vs Intel Core i5-10310Y vs Intel Celeron 3965U

Intel Core i5-7500T

The Intel Core i5-7500T is a power efficient desktop quad-core based on the Kaby Lake architecture. It was announced early 2017 and offers four cores and no HyperThreading (only 4 threads). The CPU clocks between 2.7 and 3.3 GHz. The integrated Intel HD Graphics 630 graphics card offers 24 EUs clocked at 350 to 1100 MHz. The TDP is specified at only 35 Watt and therefore even lower than mobile HQ quad cores (45 Watt). Thats why the CPU is also used in some laptops.

Intel Core i5-10310Y

The Intel Core i5-10310Y is a extremely power efficient quad-core SoC for small laptops and tablets based on the Comet Lake (CML-Y) generation and was announced in August 2019. Compared to the similar Amber Lake processors (e.g. Core i7-8500Y), the only difference are two additional cores in the top models (except i3-10110Y). The processor cores are clocked between 1.1 and 4.1 GHz (all 4 cores 2.8 GHz max). Thanks to HyperThreading 8 threads can be used. Compared to the faster i7-10510Y, the level 3 cache is reduced to 6 MB and the clock rates are lower.

Performance

While we have not tested a single system built around the 10310Y as of August 2023, it's realistic to expect the chip to be about half as fast as the Core i5-10210U (Comet Lake, 4 cores, 8 threads, up to 4.2 GHz) in multi-thread workloads. Those 4 cores of the 10310Y are set to be very much constrained by the low TDP target leading to high DPC latencies and generally unresponsive system behaviour no matter the activity.

The integrated graphics adapter is still the same as in the previous generations. It should be still called Intel UHD Graphics 615 and clock from 300 - 1050 MHz in the i5. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder.

The chip is now produced in the 14nm++ process (Amber Lake Y was 14nm+) but not 10nm like Ice Lake Y. The TDP is specified at 7 Watts but can be varied from 5.5 to 9 Watt from the manufacturer (cTDP up/down) resulting in different performance (especially Turbo durations).

Intel Celeron 3965U

The Intel Celeron 3965U is an ULV (ultra low voltage) dual-core SoC based on the Kaby-Lake architecture and has been launched in the first quarter of 2017. The CPU can be found in ultrabooks as well as normal notebooks. In addition to two CPU cores without Hyper-Threading clocked at 2.2 GHz (no Turbo Boost), the chip also integrates an HD Graphics 610 GPU and a dual-channel DDR4-2133/DDR3L-1600 memory controller. The SoC is manufactured using a 14 nm process with FinFET transistors.

Architecture

Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.

Performance

Due to the missing Turbo Boost and the low clock speeds, especially the single thread performance is very limited which results in a lower performance even for lower demanding tasks. The performance should be between the Intel Pentium 4405U and 4415U. Still, the CPU has sufficient power for office and multimedia purposes.

Graphics

The integrated graphics unit called HD Graphics 610 (similar to the HD Graphics 510) represents the "GT1" version of the Kaby Lake GPU (Intel Gen. 9). Its 12 Execution Units, also called EUs, are clocked at 300 - 900 MHz and offer a performance somewhat below the older HD Graphics 4400. Only a few games of 2015 can be played smoothly in lowest settings.

Power Consumption

Specified at a TDP of 15 W (including CPU, GPU and memory controller), the CPU is best suited for small notebooks and ultrabooks (11-inches and above). Optionally, the TDP can be lowered to 10 watts (cTDP down), reducing both heat dissipation and performance and allowing even more compact designs.
