It's been nearly 3 years since AMD last released a CPU (APU) with integrated graphics on a desktop platform...... [covers face]
In the past, it was called "APU", "Accelerated Processing Unit", "Accelerated Processor" products are actually CPUs with stronger integrated graphics, which are used to distinguish them from ordinary CPUs, after all, these years CPUs generally have a bright integrated display, but later AMD abandoned this name, and the title "APU" gradually faded out of sight, but with the release of a new generation of Ryzen 8000G, I think "APU" The title can be re-introduced - but this time it has a new meaning: "AI Processing Unit"!
Product Specifications:
There are a total of four Ryzen models of the 8000G series released this time, and the first two are actually sold, namely Ryzen 7 8700G and Ryzen 5 8600G, in a word, in fact, it is said that the desktop version of the mobile platform codenamed Phoenix released about a year ago Ryzen R7 7840H/HS and R5 7640H/HS, the difference is that the default power consumption has been increased to 65W, and the frequency of the integrated graphics card has also been greatly increased, but the CPU core frequency is not much different from the mobile terminal. Obviously, AMD intends to further expand the performance advantages of integrated graphics cards and achieve the achievement of "integrated graphics to eliminate independent graphics"!
In addition, 8700G and 8600G are also the first desktop platform CPUs with built-in AI units, needless to say how popular AI is, although the current AI applications are mainly running from the graphics card, but the XDNA AI unit built in the CPU will definitely play a greater role in the future - not to mention that the integrated graphics card of the 8000G series is already very strong!
Test platform
However, in order to test the impact of high-frequency memory on the performance of the integrated graphics card, a set of relatively high-end memory was used, and the previous generation APU 5700G and i5 13490F+GTX1650/GTX1050TI/Arc A380 were added as the control group, and the specific configuration is as follows:
CPU:AMD Ryzen 7 8700G

The packaging of the 8700G series follows the usual style of the Ryzen AM5 series, but it is different from the others: the regular version of Ryzen does not have a special logo, and the X3D version adds a silver triangle logo of "3D V-Cache technology", while in the 8000G series, it is a bright orange "AMD Ryzen AI" logo, indicating that this is the new 8000 series processor with built-in Ryzen Ai unit.
Inside, it's mostly the CPU, documents, and cooler.
The appearance of the CPU is slightly different from the previous version, although it is still an "octopus" shape, but the components such as the capacitor and resistor exposed on the top cover have been moved to the top cover, which is not afraid of silicone grease overflow!
The stickers were also changed to the new Ryzen 8000 series stickers, but this time there were no stickers for the graphics card.
Compared to the previous generation APU R7 5700G, it was already three years ago!
Unlike 5700G, this time 8700G is given to the mid-range ghost Wraith Spire radiator, that is, the one with no lights, a little thicker, pure aluminum heat dissipation, the quality is not bad, and the heat dissipation performance is better than that given by 5700G Stealth is better, but it's not as good as the ghost RGB with RGB in the 7900 Zhiku Edition, but it's completely enough for the nominal TDP of only 65W8700G, if you don't overclock, you basically don't need to buy a separate radiator, which is invisible and saved.
The motherboard that is tested is the ASUS ROG Strix B650-A GAMING WIFI blowing motherboard, which is also a veteran, and the B650 large board is a mid-to-high-end main product, which can smoothly support 8000G series APUs after updating the latest BIOS.
Since it's a white blowing snow motherboard,The heatsink is also completely white,For the default only 65W TDP8700G is a bit of a waste to make a water cooling,If you don't use the original radiator, let's have a single tower to dissipate it,After all, you have to test the performance of unlocking power consumption,Here I use Kyushu Fengshen's Ice Cube AK500S,White ARGB god light synchronization,Single fan5Heat pipe,Even the top cover and heat dissipation fins are white,Perfect match for B650A snow blowing motherboard。
Although the nominal memory support of 8700G is JEDEC DDR5 5600, according to the previous experience of using AM5 CPUs, frequencies such as 6000-6400 can give full play to the maximum performance, but from the experience of 5700G, because the APUs are all integrated IODs, FCLK overclocking capabilities are a little higher than that of CPUs with separate IODs. In addition, Ryzen's BIOS has recently been updated with the new AEGSA, and the memory overclocking ability has skyrocketed, and it is easy to get up to 8000 when the FCLK frequency is locked! For the APU with integrated graphics card, high-frequency memory should have a lot of help, so the Kingston Fury Renegade 7200 24GB×2 high-end memory package is used here, respectively, to test the 6400 and 8000 memory frequencies, and take a look at the performance of 8700G at different memory frequencies.
Default performance test
CPU performance
The first is the CPU part, based on the lower 6400 memory frequency test, in short, the single-core performance and the 7840HS on the mobile/mini host platform, unlocked to 65W, exactly the same! Of course, because the memory frequency of the desktop platform is at least 6000, the actual performance is stronger than the 7840HS 65W of the mobile platform, not to mention that even if it is a mini host, there are few that can stabilize 65W for a long time, so the multi-core performance is slightly stronger.
Integrated graphics theoretical performance
The performance of the integrated graphics card is different: on the one hand, the upper limit of power consumption is higher, on the other hand, the frequency of the Radeon 780M graphics card in the 8700G is as high as 2.9GHz, which is nearly one percent higher than the Radeon 780M 2.7GHz integrated on the mobile terminal, and it is almost one of the most frequent graphics cards in history! In addition, the higher power consumption limit of the desktop platform also further unleashes the performance of the graphics card, and most importantly, the desktop platform has extremely high memory specifications, which can provide more memory bandwidth for the bandwidth-tight integrated graphics card!(Although it is still tight, after all, the RX6400 memory bandwidth of the same core size has 128GB/s)
In the state of DDR5 6400, the performance of the 8700G integrated graphics card is already better than the performance of 7840HS+LPDDR5 6400MHz, which can almost be regarded as a downclocked version of the RX6400!
Integrated graphics for gaming performance
Even at 1080P resolution, you can basically play most of the current 3A games smoothly - and it is high image quality!Even if it is the most basic 6400 memory frequency, 8700G built-in high-spec integrated graphics card, in 1080P high image quality, all exceed the minimum playable standard of 30fps, slightly reduce the image quality, or optimize the game, you can play!
Temperature and power consumption
After all, the full load is only 65W, which is really a level that can be done with a radiator, and the input of the entire platform is only about 100W when fully loaded, of which the APU will run to about 87W first, and then drop to 65W after about 5 minutes and continue, this time and power consumption can be adjusted.
Memory overclocking and comparative testing
To be honest, there is no big surprise in the default performance, and the 65W 7840HS is about the same on the mini host, so what is the biggest advantage of the desktop platform?
Then the power consumption is unlocked!Run directly to111W,The whole machine input165W,It's about half of the default state,The temperature has also risen to 84 degrees,Fortunately, the noise has basically not increased,The whole core can run to4.7GHz,It's almost the level of R7 7700X,It's quite strong!
So what is the performance of the integrated graphics card in the state of this 8000 memory frequency? Directly pull a few independent graphics cards to compare! Here pull up the i5 13490F, which has the largest shipment volume in the mid-range of Intel, with GTX1050Ti 4G, GTX1650 D6 4G, Arc A380 three thousand-yuan independent graphics cards for comparison, as well as the Vega8 of the previous generation APU 5700G, and the UHD770 built in the 14th generation Core i9 as a reference:
It can be seen that even the default state of 65W+6400 memory8700G, its integrated graphics card performance has completely crushed GTX1050Ti, and under the double BUFF of unlocking power consumption +8000 memory frequency, the performance catches up with GTX1650 D6 high-frequency version and Arc A380, almost at the level of RX6400! Or in other words, it exceeds the GTX960 level and is close to GTX970!
One More Thing......
In addition, the Radeon 780M based on the RDNA3 architecture also supports the latest features, such as AI mapping:
At 6400 video memory frequency, the time to generate a graph of 512×512 20 iterations with the unoptimized DirectML engine is about 40 seconds to 1 minute, if you change to the optimized Onnx model, it only takes about 10 seconds! Unexpectedly, the cheapest AI graphics card with large video memory is 8700G!
In addition, in the new 24.1.1 driver, AMD has also turned on AFMF AI frame insertion support for all RDNA2 and 3 architecture graphics cards!In all 3D games and video playback, you can use AFMF to get 80-100% fps improvement! The integrated Radeon 780M can also get a huge boost, which has to say that Su Ma is atmospheric!
For example, in the 2077 image quality test, the scene is 59-61 fps when AFMF is not turned on, and it immediately skyrockets to 99fps after AFMF is turned on!
The lower the frame rate, the more obvious the AFMF effect is, for example, in the scene of Tomb 11, the original frame rate of about 40 can be doubled to about 70!But a little extra delay will be introduced in this state, and the increase is small but the delay is small under high FPS, so it is not recommended to open it in intense online games and FPS games!!
summary
1. This is the first integrated "big graphics card" on the AM5 platform"APU", although this generation of AM5 CPU has integrated the graphics core in IO Die, but in contrast, the Radeon 780M "big graphics card" in the APU really announces with powerful performance that the era of low-end independent graphics has officially passed, and even supports ray tracing and AI, with strong performance and comprehensive functions, it's time to unplug the independent graphics card to improve performance!
2. In addition, the 8000G series APU is also the first processor product with built-in AI unit "NPU" officially launched on the desktop platform. Not to mention the popularity of AI in the past two years, it is also the growth point of the next PC market. As the first processor with a built-in AI unit, it is expected that many AI-related desktop applications will be developed around the NPU in the future, which is of great significance.
3. Judging from past experience,APU prices were high at the beginning of the release,This time it caught up with the New Year,8700G The official price of the National Bank has not yet come out,But it must not be low,So friends who are not in a hurry to try the new do not worry,Equipped with7840HSThe mini host has been rolled up to the early 2000s You can buy a barebones,Add a memory hard disk is less than 3000,I believe that the CPU is almost the same8700G The follow-up price will not be too high,8600G performance is also worth looking forward to。 When the price of the 8000G series APU drops to the right price, it will be the day when the low-end independent graphics card will be completely eliminated!
