AMD FX-7500 vs Intel Core m3-7Y30 vs Intel Core i3-7100H

AMD FX-7500

The AMD FX-7500 is a power efficient ULV (Ultra Low Voltage) quad-core processor based on the Kaveri architecture. It was revealed in June 2014 for notebooks and is manufactured by GlobalFoundries using a 28 nm SHP process. In addition to having two CPU modules for a total of four integer cores clocked at 2.1 - 3.3 GHz, the AMD chip also integrates a Radeon R7 GPU clocked at up to 553 MHz with 384 GCN shaders and a dual-channel DDR3-1600 memory controller.

Architecture 

Kaveri is the successor to the 2013 Richland architecture (e.g. A10-5750M). The revised CPU cores, codenamed Steamroller, represent the third generation of the module-based Bulldozer design. A number of major changes include modified decoders (now one per integer core), optimized branch prediction, and increased L1 I-cache from 64 KB to 96 KB per module. These revisions boost the performance per clock slightly over a similarly clocked Richland APU. For more details about the AMD Kaveri architecture, see our detailed analysis here:

Analysis of the AMD Kaveri Notebook Platform

Performance 

According to the clock rates, the FX-7500 offers a CPU performance similar to the Haswell-based Intel Core i3-4100U. Overall, the FX-7500 is sufficient for all daily workloads (Office, Internet browsing, multimedia) as well as light multitasking.

Graphics

The Radeon R7 (Kaveri) GPU of the FX-7500 features a core clock of up to 553 MHz and 384 shader units. Since the GPU is based on AMD's GCN 1.1 architecture, both DirectX 11.2 "Tier 2" and Mantle are supported. Furthermore, the GPU can be used for general purpose computing in various applications, such as Adobe Photoshop via the OpenCL API. 

In terms of 3D performance, the GPU is roughly as fast as a dedicated GeForce GT 720M and can handle many current games at low or medium settings at (W)XGA resolution.

Power Consumption

The power consumption of the entire APU is rated at 19 Watts, which is somewhat above the Haswell ULV CPUs from Intel (15 W including chipset). Nevertheless, the FX-7500 is suited for 12 - 13-inch notebooks or larger.

Intel Core m3-7Y30

The Intel Core m3-7Y30 is a very efficient dual-core SoC for tablets and passively cooled notebooks based on the Kaby Lake architecture and was announced in the end of August 2016. The CPU consists of two processor cores clocked at 1.0-2.6 GHz (2-core Turbo not specified yet). 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. It is still produced in a 14 nm process with FinFET transistors. 

Architecture

Intel basically used the familiar micro architecture from the Skylake generation, so the per-MHz performance is identical. Only the Speed-Shift technology for faster dynamic adjustments of the voltages and clocks was improved, and the matured 14 nm process now also enables much higher frequencies and better efficiency than before. 

Performance

Since Intel basically removed the Core m5 and Core m7 series or included them into the higher i5 and i7 series, respectively, the m3-7Y30 is officially the last Core-m chip. Thanks to its high Turbo clock, the 7Y30 can sometimes keep up with the 15 Watt models for short peak load and single-thread scenarios, but the clocks will drop significantly under sustained workloads. The CPU is still suitable for many more demanding applications as well as multitasking. Thanks to the improved efficiency, the CPU can often even beat the Core m5 and m7 siblings from the previous Skylake generation.

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 900 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 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 an improved 14 nm process with FinFET transistors, so the power efficiency was once again improved significantly. The typical TDP for the Y-series is specified at 4.5 Watts, and can be adjusted in both directions depending on the usage scenario.

Intel Core i3-7100H

The Intel Core i3-7100H is a dual-core processor for notebooks based on the Kaby Lake architecture and was announced in January 2017. It is probably based on the quad-core die from the other H-series processor with two deactivated cores considering the TDP and the integrated HD Graphics 630. The two CPU cores run at 3GHZ without a Turbo, and the processor can execute up to four threads simultaneously thanks to Hyper Threading. It is also equipped with an Intel HD Graphics 630 GPU, a dual-channel memory controller (DDR4) as well as VP9 and H.265 video decoding as well as encoding. The chip is still manufactured in a 14nm process with FinFET transistors.

Architektur

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

Compared to the similarly branded, but much more efficient Core i3-7100U (2.4 GHz, 15-Watt TDP), the i3-7100H has much higher clocks and the performance is almost on par with theCore i5-7200U (2.5-3.1 GHz).

Graphics

The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 950 MHz in this case. The performance depends a lot on the memory configuration. Compared to HD 620 GPUs, the higher TDP could result in better sustained performance.

Contrary to Skylake, Kaby Lake now supports hardware decoding for H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors, which were announced in January, should also support HDCP 2.2.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency even further. The TDP is pretty high for a dual-core processor at 35 Watts, so the CPU is not suited fpr thin and light notebooks (where the i3-7100U comes into play).
