AMD Ryzen 7 2700 vs AMD Ryzen 5 3580U

AMD Ryzen 7 2700

The AMD Ryzen 7 2700 is an eight-core desktop processor that can handle sixteen threads simultaneously thanks to Simultaneous Multithreading (SMT). This technology is equivalent to Intel's Hyper-Threading. Launched in April 2018, the Ryzen 7 2700 is the second fastest Ryzen 7 processor and is much more economical than its flagship sibling. The Ryzen 7 2700 has a 65 W TDP, which is nearly 50% more efficient than the 105 W TDP Ryzen 7 2700 X. This energy efficiency comes at a cost to performance though.

The Ryzen 7 2700 has a base clock speed of 3.2 GHz, which can be boosted by Extended Frequency Range (XFR) up to 4.1 GHz. The power gain is still high in multi-threaded applications, although this is some way off the Ryzen 7 2700X. The Ryzen 7 2700 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 7 2700's eight 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 7 2700 has good performance in games. However, if it is operating at a lower base clock because of low TDP, then the Ryzen 7 2700 falls behind the Ryzen 5 2600 in gaming benchmarks. This behaviour could be because many games currently lack multi-core support. Hence, games rely more on clock speed more than core count.

AMD Ryzen 5 3580U

The AMD Ryzen 5 3580U, a Microsoft Surface Edition chip, is a mobile SoC that was announced in October 2019 as part of the Surface Book 15. It combines four Zen+ cores (8 threads) clocked at 2.2 - 3.8 GHz with a Radeon RX Vega 9 graphics adapter with 9 CUs (576 Shaders) clocked at up to 1300 MHz. Compared to the similar Ryzen 5 3500U, the 3580 integrates a faster GPU with 9 instead of 8 CUs.

The Picasso SoCs use the Zen+ microarchitecture with slight improvements that should lead to a 3% IPS (performance per clock) improvements. Furthermore, the 12nm process allows higher clock rates at similar power consumptions.

The integrated dual-channel memory controller supports up to DDR4-2400 memory. As the features of the Picasso APUs are the same compared to the Raven Ridge predecessors, we point to our Raven Ridge launch article.

Performance

The average 3580U in our extensive database is in the same league as the Core i5-1035G7 and also the Core i7-10510U, as far as multi-thread benchmark scores are concerned. This is a fairly decent result, as of mid 2021.

Power consumption

This Ryzen 5 has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop manufacturers - or should we say, Microsoft - are allowed to change to anything between 12 W and 35 W with clock speeds and performance changing correspondingly. Those values are not low enough to allow for fan-free designs, for better or worse.

The CPU is built with a fairly old, as of late 2022, 12 nm process for lower-than-average energy efficiency.
