Intel Core i7-7700T vs AMD A6 Pro-7050B

Intel Core i7-7700T

The Intel Core i7-7700T is a fast quad-core processor for desktops based on the Kaby Lake architecture and was announced in January 2017. It is the top model of the 35 Watt models and significantly slower than the similar named Core i7-7700K. The four Skylake based CPU cores are clocked from 2.9 - 3.8 GHz and support HyperThreading / SMT (8 threads).

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

The performance of the i7-7700T is slightly faster than the Core i5-7600K with sufficient cooling and TDP settings. Therefore, the CPU is fine to handle even demanding tasks and apps.

Graphics

The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 1150 MHz. The performance depends a lot on the memory configuration; it should be comparable to a dedicated Nvidia GeForce 920M in combination with fast DDR4-2133 dual-channel memory.

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.

AMD A6 Pro-7050B

The AMD A6 Pro-7050B is a power efficient ULV (Ultra Low Voltage) dual-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 one CPU module for a total of two integer cores clocked at 2.2 - 3.0 GHz, the AMD chip also integrates a Radeon R4 GPU clocked at up to 533 MHz with 192 GCN shaders and a dual-channel DDR3-1600 memory controller.

Technically, the 7050B is almost identical with the consumer model A6-7000. However, AMD guarantees an especially high stability and durability for the business-oriented Pro-Series.

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 

The A6 Pro-7050B offers a relatively low CPU performance somewhere between an Intel Atom Z3735G and Pentium 977. Overall, the 7050B is sufficient for simple everyday workloads (Office, light browsing, multimedia), but will struggle in more demanding applications or multitasking.

Graphics

The Radeon R4 (Kaveri) GPU of the A6 Pro-7050B features a core clock of up to 533 MHz and 192 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 the Intel HD Graphics (Haswell) or HD Graphics 4000. Limited by the CPU performance, however, only a few older and less demanding games such as Trackmania will run fluently in (very) low settings.

Power Consumption

The power consumption of the entire APU is rated at 17 Watts, which is somewhat above the Haswell ULV CPUs from Intel (15 W including chipset). Nevertheless, the A6 Pro-7050B is suited for 12 - 13-inch notebooks or larger.
