Although we always focus on the issue of risers for games, it is true that there are other very different uses of having to acquire one of these models, although in most cases a weaker one. is sufficient and according to the data we have seen in months, it seems that there is no difference in performance when using PCIe 3.0 or PCIe 4.0.
So why use a PCIe 4.0 riser card with the additional cost it entails?
As they say, if it’s not for gaming, it’s more than likely that with a quality PCIe 3.0 we’ll have enough. But a “new” technology has changed the paradigm of the video game industry and at the same time of the Riser.
We are talking about Resizable BAR, through which now the processor, memory and VRAM have no simultaneous access limitation and can exchange textures without them being in packages of 256MB. So now, as we let’s say they have free access and that means the latest engines implement the corresponding improvements so that much heavier texture packs are transferred between them.
We are talking about nanoseconds between VRAM and GPU exchanges, so being able to have the bandwidth available with VRAM is very important from the system RAM, and here is the advantage of using a PCIe 4.0 riser, especially if you are playing in high resolution and with a large number of filters.
The best PCIe 4.0 risers on the market
That being explained, you are probably wondering which are the most complete models, which ones can give us the best returns and which are the safest. Here we must clarify that there are currently few models compared to PCIe 3.0 that have more time, but fortunately the number is increasing, especially those that are high end.
So let’s get to know them better.
LINKUP Ultra PCIe 4.0 Short
We are talking about one of those extremely compact lifts, perfect for ITX equipment where every millimeter is vital. It is obviously PCIe 4.0 compatible and that includes all NVIDIA RTX 3000 GPUs and AMD RX 6000 GPUs.
The brand certifies more than 64 Gb / s bidirectional in PCIe 4.0 x16, the performances are therefore guaranteed without any doubt. This is possible because it is designed with a maximum impedance of only 0.85 ohms for GPUs or NVMe.
LinkUp guarantees a single closed and individual path for each group of lines, thus avoiding external EMI / RFI and interference between channels, which often generates errors and causes BSODs in PCs or unexpected crashes.
Its length is only 10 cm, it has a safety lock and frame anchors.
LINKUP Riser PCIe 4.0 90º Angle
With this riser we are talking about what is perhaps the best on the market turned 90º which will make it easy to install in many chassis. Its connectors are made of 24 carat gold, ensuring the best signal transmission. The brand also guarantees more than 64 Gb / s bidirectional thanks to the double layer design with earth connection, where in addition the lines are separated to improve the temperature of the cables.
It logically has an EMI / RFI shielding, the power cables are 28AWG thanks to a 4-layer PCB.
LINKUP Ultra PCIe 4.0 X16 Long
This riser has the particularity of being a so-called Double reverse, so that it can be “forced” at the angles in relation to the slot for almost impossible assemblies, especially in ITX cases. It has been tested with the NVIDIA RTX 3000 and RX 6000 ensuring all its bandwidth.
Due to its particularity, the manufacturer does not recommend the use of screws, as this can force the PCIe to anchor or move the riser, an important detail to avoid problems.
Of course it incorporates cables and connectors with an impedance of 0.85 ohm, EMI / RFI shielding.
KALEA PCIe 4.0 x4 angle 90 á
We are talking about a high quality x4 Riser which is logically compatible with PCIe 3.0 and PCIe 4.0. The part of the board is a printed circuit board that allows you to install it at 90º from the horizontal axis. Said PCB has high quality solder points, where in addition the connectors are gold plated, which allows to offer the best signal.
As expected, it includes EMI / EFI shielding for each channel. It is 23cm long, more than enough for any normal box.
