Intel Core i5-7500T vs Intel Celeron N3060 vs Intel Core i7-7700T

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 Celeron N3060

The Intel Celeron N3060 is a low-end dual-core SoC for notebooks, which has been presented in April 2015. It is clocked at 1.6 - 2.48 GHz and part of the Braswell platform. Thanks to its new 14 nanometer low-power process (P1273) with tri-gate transistors, energy efficiency has been significantly improved compared to its predecessor architecture Bay Trail (e.g. Celeron N2840). The N3060 is successor (refresh) to the Celeron N3050 and compared to it it offers a improved Turbo clock rate (2.48 vs 2.1 GHZ).

In addition to the CPU cores, the SoC offers a DirectX 11.2-capable GPU as well as a DDR3L Memory Controller (2x 64 bit, 25.6 GB/s).

Architecture

The processor cores are based on the Airmont architecture, which is basically a slightly modified shrink of the previous Silvermont core. While performance per clock has not been improved, the more efficient 14 nm process leads to a better utilization of the CPU Burst (alias Turbo Boost) and a therefore somewhat higher overall performance.

Performance

Depending on the cooling of the SoC, the Boost clock rate of 2.48 can be held for longer periods and therefore leading to a faster performance as the older Celeron N3050 that can only reach 2.16 GHz. Using Windows, the CPU is adequate for simple everyday tasks such as light Internet browsing or office applications, but not for complex software or modern games.

Graphics

The HD Graphics 400 (Braswell) is based on the Intel Gen8 architecture, which supports DirectX 11.2 and is also found in the Broadwell series (e.g. HD Graphics 5300). With 12 EUs (Execution Units) and a clock speed of up to 600 MHz, the GPU is almost twice as fast as the HD Graphics (Bay Trail), but still not powerful enough to handle modern 3D games. The GPU also supports 4K/H.265 video acceleration. Although featuring a different name, the GPU was not changed from the N3050 (named HD Graphics alone).

Power Consumption

The entire SoC is rated at an TDP of 6 watts (SDP 4 watts). Thus, the chip can be cooled passively.

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.
