Intel Core i3-2312M vs Intel Core i7-8500Y

Intel Core i3-2312M

The Intel Core i3-2310M is a dual core processor for laptops. It is based on the Sandy Bridge architecture and offers Hyperthreading to handle 4 threads at once (for a better usage of the pipeline). Compared to the faster Core i5, the i3 does not offer the Turbo Boost technique for the CPU part and is therefore clocked at 2.1 GHz (max). In difference to the similar Core i3-2310M, the 2312M can be upgraded to the Core i3-2393M which has a 400 MHz higher core frequency and a 1 MB larger last level cache than the Core i3-2312M.

Intel Core i7-8500Y

The Intel Core i7-8500Y is a very efficient dual-core SoC for tablets and passively cooled notebooks based on the Amber Lake generation and will be announced around August 2018. It is the fastest Amber Lake-Y CPU at the time of announcement and consists of two processor cores clocked at 1.5 - 4.2 GHz. Thanks to Hyper Threading, the processor can execute up to four threads simultaneously. The chips also includes the Intel HD Graphics 615 GPU, a dual-channel memory controller (DDR3L/LPDDR3) as well as VP9 and H.265 video de- and encoder. Compared to the Kaby Lake-Y predecessors (e.g. Core i7-7Y75), Amber Lake uses the same architecture produced in the improved 14nm+ FinFET process (no 14nm++) but offers higher clock speeds at an increased TDP rating.

Architecture

Intel basically used the familiar micro architecture from the Skylake / Kaby Lake generation, so the per-MHz performance is identical.

Performance

The performance of the Y series is highly depending on the cooling solution of the laptop / tablet and the TDP settings for sustained load. Therefore, the differences between a Core m3 and a i7 may be rather slim, if the thermals are very limited. The high Turbo clock speeds in Amber Lake should however lead to a very good single thread performance for short bursts.

Graphics

The integrated Intel HD Graphics 615 GPU has 24 Execution Units (EUs) like the old HD Graphics 515 and runs with clocks between 300 and 950 MHz in combination with this processor. The performance heavily depends on the TDP limit as well as the memory configuration; with fast LPDDR3-1866 RAM in dual-channel mode, the GPU should sometimes be able to compete with the HD Graphics 520, but can also be much slower in other scenarios. Modern games from 2016 will, if at all, only run smoothly in the lowest settings.

Contrary to Skylake, Kaby Lake and Amber Lake now also supports hardware decoding for H.265/HEVC Main10 with a 10-bit color depth as well as Google's VP9 codec.

Power Consumption

The chip is manufactured in the second generation 14 nm+ process with FinFET transistors. The typical TDP for the Amber Lake Y-series is specified at 5 Watts (previous generations were 4.5 Watt), and can be adjusted in both directions depending on the usage scenario.
