Intel Core i5-8265U vs AMD Ryzen 5 2600

Intel Core i5-8265U

The Intel Core i5-8265U is a power efficient quad-core SoC for notebooks and Ultrabooks based on the Whiskey Lake generation and will probably be announced in August 2018. Compared to the similar named Kaby Lake-R processors (e.g. Core i5-8250U), the Whiskey Lake CPUs are now produced in a further improved 14nm process (14nm++) and offer higher clock speeds. The architecture and features are the same. The i5-8265U offers e.g. high Turbo clock speeds of 3,9 GHz (versus 3,4 GHz of the i5-8250U) for a single core (3.8 for two cores, 3.7 GHz for all four cores). The integrated GPU is still named Intel UHD Graphics 620 and the dual-channel memory controller still supports the same RAM speeds as Kaby-Lake-R (DDR4-2400 / LPDDR3-2133). Thermal Velocity Boost is not supported (only in the Core i7-8565U).

The Whiskey Lake SoCs are used with a new PCH produced in 14nm that supports USB 3.1 Gen 2 (10 Gbps) and CNVi WiFi/BT parts.

Architecture

Intel basically uses the same micro architecture compared to Skylake and Kaby Lake, so the per-MHz performance does not differ. That means Whiskey Lake is a Kaby Lake chip manufactured in the improved 14nm++ process.

Performance

The performance of the i5-8265U depends on the cooling solution of the laptop and the defined TDP limits for short and long term performance. We already saw big differences for Kaby Lake-R (e.g., i7-8550U benchmarks), especially for long term (sustained) performance. Therefore, it will be interesting to see how the additionalTurbo  clock speed can be made use of. For the Core i7, Intel estimates between 3-11% higher performance to the Kaby-Lake-R generation and that should be similar in the Core i5 (as long as the cooling is sufficient).

Graphics

The integrated Intel UHD Graphics 620 (Intel Gen 9.5) is untouched from the 8th Gen Kaby Lake chips. With fast dual-channel memory it can reach the performance of a dedicated GeForce 920M.

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

Power Consumption

The chip is manufactured in a further improved 14nm process with FinFET transistors (14nm++), the same as the 8th Gen Coffee Lake processors. Intel still specifies the TDP with 15 Watts, which is typical for ULV chips. Depending on the usage scenario, the TDP can vary between 7.5 (cTDP Down) and 25 Watts.

AMD Ryzen 5 2600

The AMD Ryzen 5 2600 is a six-core desktop processor that can handle twelve threads simultaneously thanks to Simultaneous Multithreading (SMT). This technology is equivalent to Intel's Hyper-Threading. Launched in April 2018, the Ryzen 5 2600 is the second fastest Ryzen 5 processor and is much more economical than its flagship sibling. The Ryzen 5 2600 has a 65 W TDP, which is nearly 40% more efficient than the 95 W TDP Ryzen 5 2600 X. This energy efficiency comes at a cost to performance though.

The Ryzen 5 2600 has a base clock speed of 3.4 GHz, which can be boosted by Extended Frequency Range (XFR) up to 3.9 GHz. The power gain is still high in multi-threaded applications, although this is some way off the Ryzen 5 2600X. The Ryzen 5 2600 benefits from AMD's new Zen+ architecture, with a greater number of instructions per cycle (IPC) and higher clock speeds than last year's Zen chips. The Ryzen 5 2600's six cores are divided into two clusters that are connected by Infinity Fabric, a subset of HyperTransport. Each cluster has its own L3 cache.

The Ryzen 5 2600 has good performance in games. Moreover, the Ryzen 5 2600 has a higher base clock than the Ryzen 7 2700. Seeing as many games currently lack multi-core support, this means that the Ryzen 5 2600 performs better than its technically superior sibling.
