Solution 4 BlookyDJ said I want to upgrade my current GPU Being a GTX 760 OEM Card To something a bit newer and within my budget like a RX 6600 XT The unfortunate thing is my Motherboard and CPU are both only PCIe Gen 3 0 Compatible I know that plugging in a 4 0 Device will have some downsides such as slower speeds

A PCIe 4 0 NVMe SSD will work in a PCIe 3 0 M 2 motherboard slot at PCIe 3 0 speeds PCI Express versions are backward compatible meaning that you can use a PCIe 4 0 graphics card or storage device on a PCIe 3 0 or PCIe 2 0 system However PCI Express will use speeds based on the lowest of the two versions for communication

You can plug a PCIe 4 0 device like a graphics card into a PCIe 3 0 slot Thanks to the flexible PCIe interface the device and the slots are cross and backward compatible You can plug in a newer device in an older place and vice versa However plugging in a newer gen PCIe device in an older gen PCIe slot can present bottlenecks

So when you connect your 4 0 16x GPU to 3 0 16x slot you ll get half the speed 16 1 GB s instead 16 2 GB s In general this is probably fine the GPUs don t use that much bandwidth especially mid end one like 3060 Ti However there is a hiccup here you can think of lanes as physical connections between CPU and GPU Some cards will

A PCIe 4 0 x16 slot can theoretically hit approximately 32 gigabytes per second GB s of data flowing in each direction while PCIe 3 0 maxed out around you guessed it 16GB s Given your graphics card s specs the max speed is 14 Gbps which is well within the reach of what PCIe 3 0 can handle They also just specify that it does

So as you can see on the topic I would like to know how are the SSD speeds of PCIe 4 0 disk in a 3 0 slot Am I at least possible to get the maximum speed that the 3 0 slot can give from the 4 0 disk As an example What would be the speed of a Samsung 500GB 980 Pro M 2 in the 3 0 slot

A Gigabyte M 2 PCIe 4 0 SSD can push 5GBps reads and 4 3GBps writes a hefty increase over PCIe 3 0 drives It gets even crazier if you run them in RAID 0 which is what Gigabyte did using a PCIe
