AMD Details Renoir: The Ryzen Mobile 4000 Series 7nm APU Uncovered

My guess at the time that the new Renoir APU was almost exactly double the Zen 2 chiplet, and I mean it was scary how close to double the size it was. At the time of the announcement of Ryzen MobileI had stated in our article that I estimated mm2 for the die size. The X was also there, so I could place the two side by side and get a reasonable reference photograph on which to do calculations. This is the point of the event where I should have remembered to bring calipers! Taking photographs of chips is actually quite hard, making sure you get them lined up perfectly to get the same perspective, but also having enough light to get clear defined silicon edges. The Zen 2 chiplet on the left, measures In our image, the chiplet measured pixels by pixels, which is a ratio of 1. In our image, the Renoir SoC measured pixels by pixels, which is a ratio of 0. If we take the corresponding pixel dimensions, that gives us This means that the die size of an eight-core Renoir APU with eight 2 nd Gen Vega compute units, according to our calculations, At Before AMD announced this new chip, there was a good deal of speculation as to how AMD would build it: either four cores with more graphics, or with eight cores and graphics only a little better. One factor of that was the die size: at mm 2one would have expected AMD to definitely use eight cores. For sub mm 2in order to maintain GPU performance, perhaps a quad-core design only have been suitable. However, AMD is claiming a great win here: eight Zen 2 cores, with frequencies at 1. All just shy of mm 2. It's worth noting that AMD's official number for the Zen 2 die size is 74 mm2. This is derived from the floorplan of the chip, which during manufacturing has additional space added to ensure clean die seperation between adjacent die prints. With calipers, what we get is that additional space, which is above AMD's quoted size. This image is not to scale. With that in mind, here are our numbers. We are living in the future.

AMD Dishes on Ryzen Mobile 'Renoir' 4000 Series: New Ryzen 9 4900H, HS-Series Chips


Now, this has changed. One new model laptop that is an example of this is the 3. This model will have several different configurations, but the review samples mostly seem to have one configuration. The naming scheme that AMD is using is confusing, for no good reason. You can also replace the stock PCIe 3. Intel now has some real competition in the mobile space. Overall, the reviews that I have read and watched have been overwhelmingly very positive. Here are a few that you might want to read or watch:. AMD has put a lot of pressure on Intel in the desktop CPU space, and is a huge favorite among people who like to build their own machines from parts. This is interesting, but has not been a huge blow to Intel, because the desktop CPU market is relatively small. AMD has been successful in certain market segments, but Intel has completely dominated the very important mobile market segment. This will give people more choices, and will force Intel to respond or face losing market share. The initial response will probably be price cuts, while long-term, Intel will have to release better products. This is good news for anyone who is looking for a new laptop. If you find this sort of content interesting, please let me know in the comments. Thanks for reading! It is pretty impressive to have a relatively small and light laptop compete so well with much larger laptops that use CPUs that draw double the power. AMD Ryzen 9 H.

AMD Ryzen 4000 “Renoir” Mobile APUs Architectural Overview: Yes, it’s Monolithic


Pre-orders are going to start in the coming days and the reviews are slated to go live no earlier than April. AMD today also confirmed the existence of the top-end Ryzen 9 SKUs with higher operating frequencies and souped-up graphics. However, these will be released at a later date tentatively Q2. First the low power 15W Ryzen U lineup:. As you can see the 15W U series is the focus. The reason being that slim form-factor notebooks are everywhere these days. Pretty every application from gaming to browsers leverage up to 8 cores nowadays. The Ryzen 5 and 7 have two variants each. Both are hex-core parts while one features SMT along with a slightly lower base clock. It also has a snazzy rear-panel with moveable LEDs, something akin to an equalizer. As you can see, the H series ditches the lower-end Ryzen 3 variant. AMD is probably leaving the U series chips for the average user while the H series will serve power-users and gamers. This clearly evident from the corresponding core counts. The former offers a lot more variety with cores while the latter is essentially a two-product catalog, one with twelve threads while the other with sixteen. Interestingly, the Ryzen 7 U features one more graphics core than the H. We covered that in a post earlier, you can catch it here:. Compared to the desktop Ryzen series, Renoir features a reduced L3 cache. In addition to this, the Ryzen parts also get a healthy MHz H boost in terms of the core clock which will have a meaningful impact in real-world scenarios especially gaming. They feature an insane 9. As far as the fine-grained architectural details are concerned, the same improvements to the front-end and back-end of the core are present as the desktop Ryzen lineup. You can read more here:. The graphics part of things is less interesting but equally impressive. However, thanks to the super-efficient 7nm node, AMD has been able to extract a lot more performance out of the old graphics parts. The overall FP32 compute horsepower increases from 1. These gains come from three areas: significantly higher graphics clock, wider memory bandwidth, and an improved Infinity Fabric design. One of the main challenges with mobile CPUs is keeping the power draw low enough so that you can extract a decent battery life out of the device. Renoir achieves this with the help of the 7nm process which is the most advanced in the industry.

Renoir achieves this with the help of the 7nm process which is the most advanced in the industry. The use of LPDDR4X and the monolithic design further cut-down the power draw and offer sufficiently higher performance per watt. There have also been several software-side and kernel improvements. There are also multiple CPU governor profiles. With Picasso, there was only one. This would lead to increased latency when the system jumped from the low-power state idle to active. Furthermore, the CPU cores had to cross multiple states to get from parked to the high-performance state. With Renoir, there are three presets and in two of them, in the active ones, are only a couple of states.

AMD Details Renoir: The Ryzen Mobile 4000 Series 7nm APU Uncovered

The notebook market has not been kind to AMD over the last decade — for a long, long time the company was only ever seen as the discount option for those on a strict budget. All that seems set to change. AMD has already made waves with its Zen 2 cores in the desktop and enterprise space, and the company has already announced it plans to put eight of those cores, along with a significantly upgraded graphics design, into a processor that has a thermal design point of 15 W. These 15 W parts are designed for ultraportable notebooks, and AMD has a number of design wins lined up to show just how good an AMD system can be. The same silicon will also go into 45 W-class style notebooks, with a higher base frequency. These parts are geared more towards discrete graphics options, for gaming notebooks or more powerful business designs. The gaming market at 45 Wthe commercial market 15W to 45W and the ultraportable market 15 W are where AMD is hoping to strike hardest with the new hardware. Since earlier this year in January, at the annual CES trade show, we saw a number of early designs based on the new Ryzen Mobile family. All of these are key design wins for different segments of the market, and the two that AMD seem to be pushing most are the Zephyrus and the Yoga Slim 7. The aim here is to have something both portable and high performance, with within the right thermal envelope, for gamers and users who need something with a bit more oomph while on the road, such as video editors who need up to 32 GB of DDR4 inside. It comes with the highest grade Ryzen Mobile 15 W U-series processor, the Ryzen 7 U, and is designed to turbo up to 25 W when needed based on the design of the chassis. AMD is working with Lenovo to source these units for press sampling, which should have been for today, however due to the world situation the shipment of these have been delayed, and users will start to see reviews from next month, even though they might be available in China before then. The commercial market will take from both sets, and later in the year we might see mini-PC manufacturers like Zotac, perhaps use one or the other to bolster their portfolio. The H series processors are split into H and HS parts. The U-series parts, by the nature of the lower TDP, ultimately have a lower base frequency than the others. AMD is also going for an interesting mix here of parts with-and-without simultaneous multithreading. The bottom processor, the Ryzen 3 U, even has half of its L3 cache disabled. This is primarily due to power — the double bandwidth of PCIe 4. Each chip has sixteen PCIe 3. AMD has designed Renoir to not need additional chips to detect which way a Type-C is connected — that is all handled on die. AMD surprised us by offering some details on the silicon here. The whole die is 9. In January, we calculated through photography the die size to be about mm 2. Considering where the company was only four years ago, surrounded in a vicious negative feedback loopthis is a significant upswing in OEM participation, putting AMD in premium designs.
