The performance is clearly faster than the old RX Vega 8 thanks to the higher clock speed and faster main memory (if used). More information is available in our dedicated article about the Raven Ridge architecture. The Vega architecture offers some improvements over the Polaris generation and now supports DirectX 12 Feature Level 12_1. Compared to the similar Radeon RX Vega 8 in the Raven Ridge generation (Ryzen 2000 Mobile), the GPU is clocked significantly higher (1.750 versus 1.100 MHz Boost, +59%). The GPU should benefit from fast dual-channel DDR4-3200 RAM (contrary to DDR4-2133 single-channel, which is also possible). The performance depends on the configured TDP (12-25 W at launch), the clocks, the cooling, and the memory configuration). The GPU is based on the Vega architecture (5th generation GCN) and has 8 CUs (= 512 of the 704 shaders) clocked at up to 1,750 MHz (Ryzen 7 4800U) or 2,100 MHz (Ryzen 9 5980HX). It is used for the Ryzen 7 APUs of the Renoir generation (Ryzen 4000 Mobile) and Cezanne (Ryzen 5000 Mobile). The AMD Radeon RX Vega 8 is an integrated GPU for notebooks. The motherboard has a PCIe 2.0 x16 lane while my card is PCIe gen 3.AMD Radeon RX Vega 8 (Ryzen 4000/5000) ► remove from comparison I found some old Acer Athlon x2 prebuilt with a PCIe x16 lane and the computer displayed a video signal no issue.ĮDIT 2: I realized I overlooked something. I also got w4100 drivers from dell to see if that would resolve the problem but was left with no change in the situation.ĮDIT: It has a high chance of being a detection over driver issue. I had the AMD Drivers installed and received this message. I did get a pop up upon one boot stating that there is no driver installed or the driver isn't functioning properly.
I also updated Windows to version 1909 without any change. I attempted booting with that setting both enabled and disabled with no result. Then under APCI configuration, the only setting of note was to enable or disable keeping PCI devices powered on. The fans did spin and the peripherals did work so at least it posts (presumably). I tried booting with both of those settings and the card in the x16 lane but no display. Under northbridge settings I could set my primary display adapter as PCIe or PCI. Well, I took another look at the bios but there isn't much to play around with.
