The eight-core 16-thread Ryzen 7 5700G marks the arrival of AMD's first 7nm 'Cezanne' Zen 3 APUs for desktop PCs. AMD plans to use the Cezanne chips to plug big price gaps in its Ryzen 5000 lineup that dominates our Best CPU list and CPU Benchmark hierarchy, but they were previously limited to the OEM market until the full retail launch on August 5, 2021. Anticipation was high, though, so we grabbed an off-the-shelf system from HP to take the Ryzen 7 5700G for a spin for an early look at performance. Now we're back to fill in the final gaps with some additional testing, including CPU overclocking.
The Cezanne chips are the first AMD APUs available at retail since the quad-core Zen+ "Picasso" models landed back in 2019. AMD actually replaced its Picasso chips with the eight-core Zen 2-powered Ryzen Pro "Renoir" series in 2020, but in a disappointing development, it reserved those chips for OEMs. Unfortunately, that means APUs with the aging Zen+ architecture were the best you could find at retail, even though AMD has already progressed through three chip generations in the interim (Zen 2, XT, Zen 3).
|CPU||Arch.||Price||Cores/ Threads||Base/ Boost Freq.||GPU Cores||GPU Freq. (MHz)||TDP||L3 (MB)|
|Ryzen 7 5700G||Zen 3||$359||8 / 16||3.8 / 4.6||RX Vega 8||2000||65W||16|
|Ryzen 5 5600G||Zen 3||$259||6 / 12||3.9 / 4.4||RX Vega 7||1900||65W||16|
|Ryzen 3 5300G||Zen 3||N/a||4 / 8||4.0 / 4.2||RX Vega 6||1700||65W||8|
AMD's decision to keep those chips off the retail market couldn't have come at a worse time. The pandemic triggered an unprecedented PC upgrade cycle right as supply chain disruptions and component shortages rocked the globe and cryptomining reemerged, all conspiring to create the most severe GPU shortage in history. With discrete GPUs nowhere to be found, the Renoir chips and their serviceable integrated GPUs would have been a godsend for gamers looking to wait out the GPU shortage, but the shortage found even AMD's last-gen Picasso chips disappearing entirely from shelves.
AMD launched its Ryzen 5000 chips in the interim, but the company's pivot to premium pricing exposed two weaknesses in its product stack, including a steep $300 minimum price of entry to the Zen 3 family and a big $150 gap between its Ryzen 5 and Ryzen 7 families. Unfortunately for AMD, Intel's Rocket Lake blasted in a few months ago and plugged those pricing gaps, catching AMD uncharacteristically flat-footed.
The Cezanne APUs, which come with Zen 3 execution cores paired with the Radeon Vega graphics engine, look to solve several problems at once. Instead of its traditional separation of the CPU and APU lines, AMD slots the Cezanne chips right into its Ryzen 5000 stack — AMD says they fill the role of the standard "non-X" models that traditionally offer more attractive price points at a given core count by sacrificing peak clock speed for a lower TDP. That means the 5700G should essentially slot in as a Ryzen 7 5800, which doesn't make a lot of sense given that AMD actually has a Ryzen 7 5800 that is OEM-only. We'll dive into that a bit more later.
According to AMD, Cezanne is the cure for all of Ryzen 5000's pricing ills, with the $359 eight-core 16-thread Ryzen 7 5700G plugging the gulf between the Ryzen 7 and 5 lineups, while the $259 six-core Ryzen 5 5600G reduces the steep price of entry to the Zen 3 lineup. Both chips also come with a bundled Wraith Stealth cooler, sweetening the deal.
AMD is still holding back several of its lower-end APUs from the retail market, but given the ongoing graphics card shortages, the Cezanne APUs could be a welcome sight for the gaming market. That is if the chips actually slot in between the performance of their Ryzen counterparts. That's a tall order given that the tradeoffs associated with their monolithic die design, which differs significantly from the chiplet-based Ryzen 5000 chips. Let's see how it all works out.

AMD Ryzen 7 5700G Specifications and Pricing
The Ryzen 5000G family spans from four to eight cores and has the Zen 3 architecture that provides a 19% IPC uplift over the Zen 2 architecture used in the previous-gen Ryzen 4000G models. AMD is only bringing the eight-core 16-thread Ryzen 7 5700G and six-core 12-thread Ryzen 5 5600G to retail, at least for now. In addition, AMD currently hasn't announced when it will bring the four-core eight-thread Ryzen 3 5300G or the 35W GE-Series models to retail. The didn't stop us from grabbing a Ryzen 3 5300G and putting it through our test suite, though. However, we won't see any significant change to our list of Best Cheap CPUs any time soon.

The 65W eight-core 16-thread Ryzen 7 5700G comes with a 3.8 GHz base and a 4.6 GHz boost clock, 16MB of L3 cache, and eight Radeon RX Vega CUs that operate at 2.0 GHz. As with all Zen 3 processors, the Ryzen 5000G chips step up from DDR4-2933 to DDR4-3200 interface, which will help boost gaming performance with the integrated GPU. Compared to the eight-core Ryzen 7 5800X, you gain the Radeon graphics engine but sacrifice 100 MHz of peak boost clocks and half the L3 cache. You also step back from 24 lanes of PCIe 4.0 support to 20 lanes of PCIe 3.0.
AMD is quite adamant that the Ryzen 5000G chips serve as the new "non-X" models for the Zen 3 family. The $359 Ryzen 7 5700G plugs the sizeable $150 gap between the $449 Ryzen 9 5800X and $299 Ryzen 5 5600X. That gap left Intel's Core i7-11700K room to operate, but AMD says the 5700G's performance slots perfectly between the other Ryzen 5000 parts and brings the advantage of the integrated Vega graphics engine. The 65W six-core 12-thread Ryzen 5 5600G comes with a 3.9 GHz base, 4.4 GHz boost, and seven Radeon Vega CUs that operate at 1.9 GHz. We already have a review of the Ryzen 5 5600G here, and we'll update it with our additional overclocking tests now that the NDA has expired. However, you can see all of the additional tests in this article, too.
The $256 5600G plugs the gap between the $299 Ryzen 5 5600X and, well, AMD's entire sub-$299 product stack. AMD's aging Ryzen 5 3600 is the only real relevant contender in this price range, and it isn't competitive with Intel's Rocket Lake Core i5-11600K or Core i5-11400, leaving Intel to reign uncontested in the budget market (as you can see in our recent 11400 vs 3600 faceoff). Based on suggested pricing, the 5600G grapples with the Core i5-11600K, but AMD has yet to address the current value budget champ, the Intel Core i5-11400.
AMD Ryzen 7 5700G Cezanne Architecture
AMD's official Cezanne launch doesn't have as much deep-dive information as usual, but that's because most of the architecture is already known: AMD uses the same SoC for the Ryzen 5000 mobile chips and the Ryzen 5000G desktop PC APUs.
The majority of the Ryzen 5000G 'Cezanne' SoC comes from the Ryzen 4000 'Renoir' SoC because AMD essentially swapped in new Zen 3 cores, leaving the I/O, 7nm Radeon RX Vega integrated graphics engine and SoC design intact, thus improving time to market.
Naturally, the chip has much more thermal and power headroom in a desktop PC, so AMD tunes multiple variables to tailor the chips for both unique segments, like power consumption, boosting algorithms, and power-sharing between the CPU and GPU. You can read much more about the design and architecture in our AMD Ryzen 5000 Mobile 'Cezanne' SoC Deep Dive.
AMD reused the Renoir SoC design, so the 5700G comes with the 7nm Radeon RX Vega graphics engine with eight CUs, and not a newer RDNA-based design. AMD has dialed back the 5700G's iGPU by 100 MHz compared to the previous-gen 4750G but increased the CPU base/boost clock rates by 200 MHz, suggesting that it tuned the SoC for an optimal balance of CPU and GPU horsepower. AMD had already reworked the graphics architecture for its last go-round with Renoir — the reworked 7nm RX Vega graphics delivered up to 60% percent more performance per compute unit (CU) than its predecessors, equating to more graphics performance from fewer CU.
Ryzen 5000G’s monolithic die allows for tighter control of power efficiency and other important characteristics for the mobile space, but it also introduces a few tradeoffs compared to the desktop chips that have a chiplet-based design. For example, unifying all the I/O, cache, and CPU cores, not to mention adding GPU cores, onto a single die inevitability resulted in some sacrifices to meet the company's performance, power, and area (PPA) targets.
For instance, the Ryzen 7 5700G has 16MB of L3 cache, but that's half the L3 capacity of the chiplet-based Ryzen 7 5800X for desktop PCs that also comes with eight cores. However, Cezanne does improve over the Renoir APUs — the 5700G has twice the L3 of the eight-core 4750G.
AMD also unified the eight cores and cache into one contiguous 16MB cluster inside the CCX (Core Complex). In contrast, Zen 2 had two four-core clusters, each with 4MB of cache. This larger unified cache improves both core-to-cache and core-to-core latency over the Renoir chips. In addition, for highly-threaded applications, this imparts a 2X cache increase, and lightly-threaded workloads now have access to a full 16MB of cache, equivalent to a 4X increase in directly-accessible cache.
Re-using the Renoir SoC design also means that AMD has stuck with the PCIe 3.0 interface found on all its current-gen APUs. As such, the chip has 20 lanes of PCIe 3.0 connectivity (16 for graphics, four for the chipset, and four for storage) compared to 24 lanes of PCIe 4.0 found on the Ryzen 5000 models for the desktop PC.
The Cezanne desktop chips will find their way into 500-series and some 400-series motherboards, though support on the latter will vary by vendor.
