Key Features Of The AMD Ryzen 5 2400G APU!
The AMD Ryzen 5 2400G APU Up Close!
The AMD Ryzen 5 2400G with Radeon RX Vega 11 Graphics (Price Check) has four Ryzen processor cores with a 3.6 GHz base clock, and a 3.9 GHz boost clock. It supports SMT (simultaneous multi-threading), and can therefore handle 8 threads simultaneously.
It uses a single CCX (CPU Complex), allowing AMD to fit a Radeon GPU on the same die. Its transistor count only increased by 3% to 4.94 billion, with a 9% larger die size of 209.78 mm².
Single CCX Configuration
Unlike the Summit Ridge-based Ryzen CPUs, the AMD Ryzen 5 2400G uses a single CCX configuration. This is a cost-saving measure that yields a much smaller die size, with some performance benefits – reduced cache and memory latencies.
AMD analysed the performance of the 2+2 and 4+0 configurations, and concluded that they are “roughly equivalent on average across 50+ games“.
Smaller L3 Cache
Using a single CCX configuration has the unfortunate effect of halving the L3 cache size from 8 MB to 4 MB. AMD increased its base and boost clock speeds to compensate for the smaller L3 cache.
The AMD Ryzen 5 2400G has a 400 MHz (12.5%) higher base clock and a 500 MHz (14.7%) higher boost clock than the Ryzen 5 1400 it replaces.
New CPU Package
The Raven Ridge APUs also introduce a revised CPU package, and a switch to the traditional non-metallic TIM (thermal interface material). These are again cost-cutting measures, albeit with a side benefit of allowing the AMD Ryzen 5 2400G (Price Check) to officially support DDR4-2933 memory.
Precision Boost 2
The AMD Ryzen 5 2400G (Price Check) supports the improved Precision Boost 2, whose more graceful and linear boost algorithm allows them to “boost more cores, more often, on more workloads“. It can change frequencies in very fine granularity of just 25 MHz.
According to AMD, this will allow the Raven Ridge processors to perform better with apps and games that spawn many lightweight threads, as opposed to apps with persistent loads (e.g. video editing and 3D rendering).
PCIe x8 For Discrete GPU
The Summit Ridge-based AMD Ryzen 7, Ryzen 5 and Ryzen 3 processors have 16 PCI Express 3.0 lanes dedicated to the PCIe graphics card. The AMD Ryzen 5 2400G (Price Check) only has half that – 8 PCIe lanes. That means any external graphics card will only communicate with it at PCIe x8 speed.
This is a cost-saving measure, although AMD also claims that the move contributed to a smaller and more efficient uncore. According to AMD, this is unlikely to make a significant difference with the type of (mid-range) graphics cards this processor will usually be paired with.
AMD Wraith Stealth
The AMD Ryzen 5 2400G (Price Check) is bundled with the AMD Wraith Stealth cooler. This is a basic CPU cooler, so don’t expect LED or RGB lighting, a copper base or even heatpipes.
The Wraith Stealth cooler uses a simple, low-profile aluminium heatsink, with a new spring-screw clamping system. Its main advantage – it’s quiet with a maximum noise level of 28 dBa.
