Updating its access-level and mid-range product traces, AMD's new Ryzen five 2400G and Ryzen three 2200G APUs are set to update the organisation's Ryzen five 1400 and Ryzen three 1200, and might even invalidate the R3 1300X and R5 1500X to a degree. Besides the revised CPU, what makes those new access degree chips special is that they arrive with incorporated Radeon Vega photos. We noticed that running pretty well some months again on laptops, however not like transportable systems, there are a long way less constraints at the desktop.
Codenamed Raven Ridge, the brand new chips are based totally on the equal 14nm manner because the unique Ryzen, although AMD is advertising those as "14nm+" process, comparable to the strategy Intel has used currently. What this essentially manner is that the manufacturing technique has matured to the point in which they can dial up the clock speeds a little greater and that is precisely what AMD has accomplished right here.
Along with a frequency enhance, Raven Ridge chips have a unmarried CCX module, which is to mention that they're confined to four cores (see our original Ryzen overview in case you're misplaced). There are pros and cons to this design, with the important thing benefit being that the latency penalty while shifting statistics between CCX modules is eliminated, even though based totally on our own checking out that hasn't regarded like a massive trouble. The advantage for AMD is that they get the same quantity of cores in a place that's half the scale.
AMD's Raven Ridge APUs at a look
Ryzen 5 2400G | Ryzen 3 2200G | |
Price | $169 | $ninety nine |
CPU Cores/Threads | four / 8 | 4 / 4 |
Graphics | Vega eleven | Vega 8 |
Base CPU Frequency | 3.6 GHz | 3.five GHz |
Turbo CPU Frequency | three.nine GHz | three.7 GHz |
L2 Cache | 512 KB/core | |
L3 Cache | 4 MB | |
GPU Cores | 704 SPs @ 1250 MHz | 512 SPs @ 1100 MHz |
Compute Units | 11 CUs | eight CUs |
RAM Support | DDR4-2933 | |
TDP | 46-sixty five W |
The drawback, on the other hand, is that you get much less CPU usual. With one CCX module, Raven Ridge's L3 cache receives reduce down from 16MB to 8MB, however AMD determined to halve it once more and these chips come with handiest a 4MB cache. Comparatively, the Ryzen 5 1400 had an 8MB L3 cache and the 1500X packed 16MB, the 2400G and 2200G will provide just 4MB. Now that doesn't sound too encouraging however AMD believes they have got been capable of offset that reduction with better clock speeds.
However, reduced latency for the cache and reminiscence purportedly offsets that potential deficit and this is really a result of having much less cache and overall AMD believes that this is a internet superb development for productiveness workloads and especially video games which are greater sensitive to memory latency.
There's additionally been a few nook-reducing to lessen manufacturing charges. Raven Ridge best packs x8 PCI Express lanes, no longer sixteen just like the first-generation Ryzen CPUs. AMD has made this sacrifice because it does not assume it will effect overall performance for mid-variety discrete photographs cards, and it is unlikely that people with an APU can be upgrading to a GTX 1080 Ti any time quickly so this makes sense.
AMD says this reduction in PCIe lanes facilitates contribute to a smaller and extra green "uncore" as properly. Uncore is a time period first used by Intel to describe factors of the CPU that aren't inside the center but are closely linked to it for max overall performance. Things such as the L3 cache and on-die reminiscence controller, as an example.
AMD has also saved money via the use of a non-steel TIM for the 2400G and 2200G. We're not positive if the organisation is using the identical toothpaste as Intel, however we'll test load temperatures to get an idea. Regardless, this confirms what we already suspected: Intel has been cheaping out on thermal paste to store on production expenses and now AMD has been doing the precise identical aspect for its maximum less costly CPUs, though as a minimum the organisation is admitting it and it additionally makes greater experience on these budget chips.
Raven Ridge parts also feature assist for twin-channel DDR4-2933 memory, that is an essential characteristic for these APUs as memory performance is of extreme importance for incorporated images. Like the cell parts, the desktop Raven Ridge CPUs game Precision Boost 2 generation, which is largely just a extra aggressive model of what became featured in the original Ryzen processors.
And of route, the most exquisite alternate is the inclusion of Vega pics. Connected to the CPU via the Infinity Fabric is a Vega chip offering 11 CUs for the 2400G and eight CUs for the 2200G. Clock speed is the principle benefit to the usage of the Vega architecture over Polaris, because the integrated graphics on each of AMD's new chips operate at over 1000MHz and can be driven to at least one.5GHz or higher.
Additionally, both elements have a thermal design energy of 65 watts, though they can be configured all the way down to 45 watts.
We'll be trying out Raven Ridge on a B350 motherboard with 16GB of DDR4-3200 memory. First we'll check application performance earlier than transferring onto gaming (with and with out a discrete snap shots card) at the side of some reminiscence scaling performance. We'll additionally be referring to overclocking, strength consumption and working temperatures so let's get to it.
