Update 02/23/24 Due to a highlighted issue with the Skin Temperature-Aware Power Management (STAPM), we retested the Ryzen 7 8700G and Ryzen 5 8600G with the latest firmware, which reflects the removal of the STAPM limitations. In the interest of full disclosure, we have kept the results from our initial review and opted to add the latest results to show any performance gains and/or regressions. We also plan to add more chips to the data in the coming days, including the Ryzen 7 7700, and more results in our integrated graphics testing with some Intel chips, including the Core i5-14600K and i5-12600K.

One of the most desired desktop chips designed for low-cost systems has been AMD's APUs, or Accelerated Processing Units. The last time we saw AMD launch a series of APUs for desktops was back in 2021, with the release of their Cezanne-based Ryzen 5000G series, which combined Zen 3 cores with Radeon Vega-based integrated graphics. During CES 2024, AMD announced the successor to Cezanne, with new Phoenix-based APUs, aptly named the Ryzen 8000G series.

The latest Ryzen 8000G series is based on their mobile-focused Phoenix silicon, and has been refitted for AMD's AM5 desktop platform. Designed to give users and gamers on a budget a pathway to build a capable-yet-cheaper system without the requirement of a costly discrete graphics card hanging over their head, the Ryzen 8000G series consists of three retail SKUs, ranging from an entry-level Phoenix 2-based Zen 4 and Zen 4c hybrid chip, all the way to a full Zen 4 8C/16T model with AMD's latest mobile RDNA3 integrated graphics.

The Ryzen 7 8700G with 8C/16T, 16 MB of L3 cache, and AMD's Radeon 780M graphics are sitting at the top of the pile. The other chip we're taking a look at today is the middle-of-the-road AMD Ryzen 5 8600G, which has a 6C/12T configuration with fully-fledged mobile Zen 4 cores, with a third option limited to just OEMs currently, with four cores, including one full Zen 4 core and three smaller and more efficient Zen 4c cores.

The other notable inclusion of AMD's Ryzen 8000G series is it brings their Ryzen AI NPU into the desktop market for the first time. It is purposely built for efficiently executing local AI inferencing workloads, using a fraction of the power and resources that the CPU or GPU cores would otherwise take.

Much of the onus on the capability of AMD's Ryzen 8000G series will be how much of an impact the switch to Zen 4 and RDNA3 integrated graphics commands over the Ryzen 5000G series with Zen 3 and Vega, which is already three years old at this point. The other element is how the mobile-based Phoenix Zen 4 cores compare to the full-fat Raphael Zen 4 cores. In our review and analysis of the AMD Ryzen 7 8700G and Ryzen 5 8600G APUs, we aim to find out.

AMD Ryzen 8000G Series: Zen 4 APUs w/ RDNA3 Graphics

As AMD strides into 2024, the spotlight is on artificial intelligence technology. The Ryzen 7 8700G and Ryzen 5 8600G models are both equipped with the embedded Ryzen AI NPU, enhancing on-chip AI inferencing capabilities. Consistent with AMD's approach in recent generations, the Ryzen 8000G series APUs are not built from entirely new silicon. Instead, they use AMD's existing monolithic "Phoenix" family of dies, which are already in use in the mobile market as the Ryzen Mobile 7000/8000 series. Both Phoenix (1) and its low-cost compatriot, Phoenix 2, are being drawn in by AMD for desktop use with the Ryzen 8000G series.

Targeting budget-conscious gamers and entry-level users, the Ryzen 8000G series amalgamates key features from the Ryzen 7000 desktop series and the Ryzen 8000 mobile series. Notably, each of the four models in the Ryzen 8000G series maintains a TDP of 65 watts. This is slightly higher than their mobile counterparts but offers more power headroom on desktops, especially useful for hitting (and sustaining) higher clockspeeds on things like the Radeon RDNA3-based graphics block.

Similar to its predecessors, including the previous Zen 3-based Ryzen 7 5700G, Ryzen 5 5600G, and Ryzen 3 5300G, the latest Zen 4 Ryzen 8000G series of APUs from AMD continues to provide the dual advantages of a unified, mobile-oriented die architecture while maintaining a strong presence in the entry-level desktop market.

Shifting focus to their intended audience, AMD offers the assurance of 'ready to game out of the box at 1080p' performance levels. 1080p remains the most common resolution among gamers by far, as indicated by the latest Steam Hardware Survey. However, it's important to note that these chips are not tailored for high-end AAA gaming at 1080p. Users looking to play more graphically demanding games should be prepared to adjust the quality settings accordingly or opt to purchase a discrete graphics card – though if you're planning on using a discrete card from the start, you may want to look at AMD's traditional CPUs.

The Ryzen 7 8700G leads the lineup, rooted in AMD's Phoenix mobile silicon, offering eight Zen 4 cores (8C/16T). This top-tier model offers a turbo frequency of 5.1 GHz and a base frequency of 4.2 GHz, which, compared to the previous Zen 3-based Ryzen 7 5700G, offers a 500 MHz bump in turbo clock speeds alone, as well as architectural advancements brought about by Zen 4.

As a true APU on AMD's AM5 desktop platform, it integrates Radeon 780M graphics based on the RDNA3 architecture, featuring advanced capabilities like Hyper-RX and Fluid Motion Frames (frame interpolation). The Radeon 780M is equipped with 12 CUs and 768 shader units (1536 ALUs), operating at a clock speed of 2.9 GHz.

Meanwhile, AMD rightly claims, the Ryzen 8000G series, with the Ryzen 7 8700G and Ryzen 5 8600G, are the first desktop processors on the market to come with a dedicated AI engine, namely Ryzen AI. On paper, the Ryzen 7 8700G is a powerhouse for on-chip AI inferencing, with AMD offering software developers an NPU, CPU, and GPU for AI inferencing, depending on their use case and performance needs.

The Ryzen 5 8600G is positioned just below the 8700G and features six Zen 4 cores (6C/12T), reaching a maximum turbo frequency of 5.0 GHz and a base frequency of 4.3 GHz. It also houses the Radeon 760M RDNA3 integrated graphics with 8 CUs and 512 shader units clocking at 2.8 GHz. Like the Ryzen 7 8700G, the 8600G model incorporates the Ryzen AI NPU engine, a technology AMD acquired through their 2022 Xilinx acquisition, highlighting both model's on-chip AI inferencing capabilities and bringing Ryzen AI directly from their mobile chipset straight to the desktop.

Although AMD hasn't sampled us with the Ryzen 5 8500G or the Ryzen 3 8300G, they are built differently than the other two Ryzen 8000G APUs. The Ryzen 5 8500G uses AMD's budget Phoenix 2 die, which blends two Zen 4 cores with four energy-efficient Zen 4c cores. The chip offers a base speed of 3.5GHz, while the big Zen 4 cores can turbo up to 5.0GHz, and the smaller Zen 4c cores have a peak clockspeed of 3.7GHz. This transition to the Phoenix 2 architecture drops the Ryzen AI NPU and scales down the integrated graphics to a 4 CU Radeon 740M with a 2.8GHz peak graphics frequency. Mirroring the mobile Ryzen 5 8540U in several aspects, the 8500G stands out with a higher 65W TDP, which is more adequately suited for AMD's AM5 desktop platform.

Complementing the lineup, the entry-level Ryzen 3 8300G, which is only being sold to system integrators and OEMs, and features a mix of one full Zen 4 core and three Zen 4c cores, with up to 4.9 GHz turbo speeds on the single Zen 4 core. This model also sees a reduction in L3 cache to 8MB, alongside 4MB of L2 cache, balancing its capabilities for basic computing tasks.

Although both the Ryzen 7000 desktop series and the Ryzen 8000G share the same AM5 platform, the way the I/O is configured between the families is different. For the Ryzen 7000 series, the chips have a total of 28 x PCIe 5.0 lanes. Of those, 24 x PCIe 5.0 are usable due to the DMI link between the CPU and the chipset using x4 of these. The Ryzen 8000G series is different in that they omit PCIe Gen 5 lanes and instead opt for PCIe 4.0 lanes, with the Phoenix (8700G/8600G) coming with 20 x PCIe 4.0 lanes, of which x16 are usable between graphics and M.2 storage. This means the Ryzen 7 8700G has a PCIe 4.0 x8 link for a graphics card (not x16), with 8 x PCIe 4.0 lanes for two PCIe 4.0 x4 M.2 SSDs.

Things get different once again when looking at the Phoenix 2-based CPUs, including the Ryzen 5 8500G and Ryzen 3 8300G, which combine both Zen 4 with the smaller Zen 4c cores. The two Phoenix 2 Ryzen 8000G processors have just 14 x PCIe 4.0 lanes in total, with only 10 x PCIe 4.0 lanes being usable. This means that a graphics card should theoretically support a bandwidth-limited PCIe 4.0 x4 for the graphics, with/or 6 x PCIe 4.0 lanes for an SSD, likely in an x4/x2 configuration. We've contacted AMD to confirm the configuration the Phoenix 2-based silicon is using, but we're still awaiting a reply.

It's also worth noting that motherboard chipset support remains the same, whether that be X670E, X670, B650E, and B650. As the Ryzen 8000G series is newer and is designed for mobile devices such as laptops, they include native support for USB4 connectivity, with two ports supported natively. They do, however, drop support for two out of four of the USB 3.2 G2 ports that are supported on the Ryzen 7000 series.

For users looking to leverage the AMD Radeon RDNA3-based integrated graphics, a motherboard with at least one form of video output is required. The Ryzen 8000G series APUs are supported by all of AMD's AM5 chipsets, including X670E, X670, B650E, B650, and A620. Users looking to use a discrete graphics card can select any AM5 board currently on the market. However, as mentioned, the iGPU requires a video output such as a DisplayPort or HDMI output.

Regarding the target audience for AMD's Ryzen 8000G series processors, they are suited to users looking to build a competent system capable of gaming at lower resolutions and offering a good level of compute performance. At the lower end of the PC hardware spectrum, price is a key characteristic, and given that Ryzen 8000G only supports DDR5 memory through the AM5 chipset, we're not seeing the same value we saw with AM4.

This brings the overall value into question, with the top SKU, the Ryzen 7 8700G, coming with an MSRP of $329, which puts it $30 cheaper than the previous Ryzen 7 5700G ($359) at launch. The Ryzen 7 5700G is currently $170 at Amazon (at the time of writing), while the Ryzen 5 5600G costs just $124 at Amazon. Tie that into the MSRP of the Ryzen 5 8600G at $229. It's also worth pointing out how much cheaper adopting the AM4 platform with DDR4 memory can be at the entry-level market, and we're looking at some stern competition. The added benefit is that the Ryzen 8000G comes with Ryzen AI and on-chip AI capabilities, along with the jump in generational performance going from Zen 3 to Zen 4, DDR5 vs. DDR4, and of course, the latest RDNA3 mobile graphics too.

    For basic use a 4 core is fine. Plenty of games still run fine on 4 cores, and if you are using the iGPU your CPU cores are not going to be your limiting factor.
  • FatFlatulentGit - Wednesday, January 31, 2024 - link

    That setup would also eat over 2x as much power. The 8000G line is for people who want something with some expansion options and decent performance, but also want to keep it lower power/heat/noise, among other things. I'm eyeballing one for an HTPC upgrade.
  • t.s - Tuesday, January 30, 2024 - link

    The problem with 8700G is the price. Too pricey. I'll take socketed CPU anytime over soldered If the price is right ($200-$250). Cause when you go 7840HS route, you can get complete packages with just $490 (16GB 5600MHz, 512GB SSD, BT5.2 + WiFi6) or about $390 no RAM no SSD.
  • GeoffreyA - Tuesday, January 30, 2024 - link

    Quite a nice boost in performance over the 5000G APUs, with only a slight increase of power. Though I suppose for those already on AM4 APUs, it may be better to wait for the Zen 5 ones, and get an even bigger boost in one shot.

    I've been reading Anandtech for decades, since it started. In all that time, this is the worst review I've ever seen. We already know these chip are budget / entry level (of the latest generation). There's only one thing that is truly interesting about these chips: The integrated graphics. And specifically, the IGP at 1080p. And while we get 4 pages full of tests of a discrete GPU with this CPU, we get a total of one page with the IGP at 1080p, and it contains only one chart comparing this chip with other options (e.g. Intel), and that one chart is of ... drum roll ... Civ6 🤦‍♂️ WTF!?!?!?!

    We do get a few more graphs of 720p gaming. Why?!? WHEN THE REVIEW ALREADY EXPLAINED THAT THE STEAM STATS SHOW MOST GAMERS PLAY AT 1080P?!?!?!?

    I'm not going to assume that this is a conspiracy theory. After all: "Never attribute to malice that which is adequately explained by stupidity."

    Come on. Do better. This article should have been centered around and anchored on the 1080p results with this chip's IGP. It should have compared with more than just AMD's previous gen of this chip; it should have compared with Intel's offerings in this space. The questions the reader has are: What $$$ video card does this thing save me from buying? Will this play my game? How does it compare with other CPUs and their IGPs?

    End rant. Do better.
  • cp0x - Tuesday, January 30, 2024 - link

    And of course (as other commenters have pointed out): What effect does slower or faster DDR5 make on the 1080p results? (Especially since faster DDR5 was actually being used in the Intel system.)
  • FWhitTrampoline - Tuesday, January 30, 2024 - link

    The tech press in general ignores iGPUs and small form factor systems save ETA Prime and his YouTube channel. But ETA Prime is Gaming Benchmark Focused there mostly so any Blender 3D Cycles iGPU accelerated testing is ignored there. AMD tends to only focus on Games development for its APUs mostly as the console makers using AMD's APUs are more responsible for the games performance on AMD's APUs than AMD is responsible.

    And really the Gaming Hardware review sights are higher end Desktop Processor/dGPU focused there where Very Small Form Factor(InWin Chopin and ASRock X300/Other Desk Mini SKUs that use AMD and Intel Socket Packaged processors with powerful iGPUs make sense) system builds are ignored!

    Both the ASRock X300/Desk Mini and the Inwin Chopin very small form factor system builds and are too tiny to accommodate any dGPUs and so Ryzen 5000G was popular there for the iGPU and in those builds with AMD/Intel APUs/SOCs with more powerful iGPUs. There will be an ASRock x600/AM5 Desk Mini and what is essentially the same case form factor as the X300/AM4 Desk Mini. The Inwin Chopin barely accommodates a Mini-ITX MB but lacks the room of any dGPU to get slotted into the x16 slot on a Mini-ITX MB, sans some case modding of the Chopin!

    1080 gaming, well, the real application for gamers running greater than a 6000 MHz memory bus is high frequency trading. mb

    I think the worst crime in the review was using DDR5-5200.
