News AMD's looming Ryzen APUs show big 30% boost over prior-gen models — Ryzen 8000G benchmarks easily beat Ryzen 5000G

[Admin]

Results for three Ryzen 8000G APUs in Passmark have been uncovered, and the new Ryzen 8000G chips are around 30% faster than Ryzen 5000G models.

Even if the graphics uplift is not as much, that's pretty big all things considered.

That type of uplift is unheard of for a while.

For comparison, a 7840HS does about 29k, and 7940HS does about 30.5k in passmark.

So, yay? 8700G is faster than its mobile counterpart.

An important feature (for non-gamer) is that both the 5700G and 8700G provide more than 8 lanes of PCIe (which was a limitation on the previous AMD APUs).

AMD 5700G: Gen 3, 16 Lanes (CPU only)
AMD 8700G: Gen 4, 20 Lanes (CPU only)

Because both include an iGPU, these PCIe lanes can be used for anything other than a GPU, if for example, your goal is server usage.

I have an AMD 5700G with an AM4 motherboard offering 16x, 8x8x, 8x4x4x PCIe bifurcation. An inexpensive bifurcation PCIe card for 8x8x (with the UEFI configured accordingly) allows the integration of (for instance) a high-speed NIC and a hardware-base RAID card. This is appropriate for a "cheap" file server or Proxmox server over 10 GbE, 25 GbE or even 45 GbE with IPoIB using a 2nd hand Mellanox ConnectX3 card from eBay.

If I were to upgrade to an AMD 8700G (I'm not as of this writing), the first thing I would do is to look for an AM5 motherboard offering bifurcation of the PCIe lanes or offering two 16x slots that can be used as 8x 8x.

I think TechPowerUp got it wrong. 5700G technically supports 24 PCIe 3.0 lanes (4 reserved for chipset). Which is why you can use it with an x16 GPU and x4 SSD:

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.

Note the confusing math in Tom's review, then see these:

The top part is a Ryzen 7 5700G, featuring eight cores and sixteen threads, with a base frequency of 3.8 GHz and a turbo frequency of 4.6 GHz. The Vega 8 graphics runs at 2000 MHz, and we get sixteen lanes of PCIe 3.0 for graphics, plus another four for storage and four for the chipset..

Common features of Ryzen 5000 desktop APUs:
...
All the CPUs support 24 PCIe 3.0 lanes. 4 of the lanes are reserved as link to the chipset.

I *believe* the 8700G/8600G have 24 PCIe 4.0 lanes (4 reserved), with the 8500G/8300G subtracting 10 lanes (leaving 8x for graphics, 2x for SSD, 4x for chipset). Not sure. AMD's own website lists 20 total / 16 usable for the 8700G, and 14 total / 10 usable for the 8500G. Yet another spec sheet mistake?

This reminds me with AMD Ryzen APUs based on Raven Ridge and Picasso dies that only provided 12 lanes user accessible PCIe 3.0-slot. If 16 lanes user accessible PCIe 4.0-slot is true, it means only 8 lanes-PCIe slot is avaliable for discrete graphics card since another 8 lanes will be used for nvme storages
