Usb 10gbps and even 5gbps is just good enough for most things and if you want more speed it makes sense to go for the more direct pcie over thunderbolt with less overhead and no protocol conversion headaches. USB4 was released at the end of 2019 and will be in integrated on-chip in TigerLake products at the end of 2020! For other products it will likely be somewhere in 2022 though. USB 3.2 20gbps was released in 2017 and only found with dedicated chips on a few 2019 strx4+x299 boards + new 2020 intel 1200 z470 boards. Just for reference, USB 3.1 10gbps was released in 2013 and often implemented with dedicated chips on mobos and finally standard chipset in 2018 with z390 and zen2/b550/x570. It seems like the market will just skip it and focus on the easier to market USB4. USB4 still only requires minimum speed of 10Gbps USB and the same is true for the TB4, ie the first wave of Intel-only controllers will likely not support USB 20Gbps either. USB4 & TB4 also won't change this it seems. Thunderbolt 3 support is widespread though. There are only a handful of high-end boards and two external SSDs ( with lots of problems), but afaik nothing else. Your issue is that nothing really supports USB 3.2 Gen 2x2 (20Gbps) though. Your numbers are right USB always had a lot of overhead. TB3 is capable of achieving 22Gbps real world, acccording to If you have USB 3.2 ports, just get or wait for the USB 3.2 versions of the above products?Įdit - I stand corrected. Įxamples of products that don't make sense with this conclusion minor real world benefit over USB 3.2 Gen 2 2x1 for data-only setups?īasically, doesn't that mean "don't get TB3 unless you absolutely need the additional displayport and eGPU functionality"? This is a striking conclusion you should not pay for TB3 surcharge if you are interested in data only transfers. Each port supports transfer rates of up to 10Gbps allowing. Connect the aluminum USB 3.1 hub to the USB port of your computer and instantly create four USB 3.1 Gen2 type-A ports. As a result, you cannot achieve transfer speeds of up to 5Gbps, but up to 10Gbps. SLOWER real world speeds than USB 3.2 Gen 2 2x2 for data-only setups and This hub is equipped with USB 3.1 Gen2 technology. Real world (data transfers only) - 7.2-8GbpsĪm I correct in concluding that TB3 (and TB4 presumably) offers The SuperSpeed logo means 5 Gbps, and the SuperSpeed+. The colorful logos are used primarily on packaging, not on devices themselves. Theoretical rate (data transfers only) - 10Gbps USB 3.1 Gen 2 with DisplayPort over Type-C with USB PD N/AN/A. Real world (data transfers only) - 16Gbps
Theoretical rate (data transfers only) - 20Gbps
Usb 3.1 gen2 type a actual speed upgrade#
USB 3.1 Generation 1 was an initial upgrade to USB 3.0, but it is limited to 5Gbps data transfer speeds, while the newer USB 3.1 Generation 2 is the spec that boosts data transfer speeds to the theoretical 10Gbps. Real world (data transfers only) - 10.2Gbps/9.6Gbps (22Gbps See edit) There are actually two distinct USB 3.1 specifications at this time. Theoretical rate (data transfers only) - 22Gbps (It's NOT 40Gbps for data only, see links below) TB3 cables and peripherals are quite expensive.
I am interested in comparing TB3 vs USB 3.2 Gen 2 for data-only transfer purposes.
