The difference and performance comparison evaluation between RTX3090ti and 3090

 

 

The number of RTX3090Ti stream processors is 10752, which is 256 more than the RTX3090, and the acceleration frequency reaches 1860MHz, which is 10% higher than the 1695MHz of the RTX 3090. The memory frequency is also increased from 19.5GHz to 21GHz. The bandwidth is directly upgraded by 1TB/s, which is also the first time that a GeForce graphics card has exceeded the 1TB/s mark. However, after the performance improvement, the TDP power consumption has also increased by 100W, and the external power supply has changed from 12Pin to 16Pin, which means that the RTX3090Ti has higher power supply requirements.

 

 

Although the RTX3090Ti and RTX3090 both have 24GB GDDR6X memory, and the RTX3090 has 24 memory particles, which need to be distributed on the front and back sides of the PCB, the RTX3090Ti has increased the memory capacity of a single memory to 2GB, which means that the graphics card has only 12 memory particles in total, all of which are placed On the front of the PCB board, the advantage of this is undoubtedly to reduce the heat dissipation pressure of the video memory and help the graphics card to reduce the temperature.

 

 

RTX3090Ti supports video memory ECC automatic error correction function, which is usually only equipped with industry graphics cards. For users who need to run scientific computing, it can solve the problem of video memory error reporting in long-term high-load applications, which is more stable. However, when ECC is turned on, it will bring a certain performance loss. Of course, in order not to affect the game experience, it will not be turned on by default. If you want to turn it on, you can set it in the NVIDIA control panel.

 

 

The RTX3090Ti uses a new PCIe 5.0 external power supply interface design, 16Pin power supply interface, of which 12Pin is responsible for power supply, and the other 4Pin is responsible for signal transmission, which is used for direct communication between the power supply and the PCIe 5.0 graphics card to determine the power supply limit.

 

However, considering the compatibility of the old-fashioned power supply, the graphics card is usually equipped with a 12Pin to 3 8Pin adapter cable. I believe many users are worried about whether it will affect the use of the 12Pin power cable converted from 3 Pins to the 16Pin of the graphics card. You can rest assured that the 4 Pin signal interface is currently not affected.

 

Let's take a look at the difference between RTX3090ti and 3090. Next, we use 3DMark software and games to test the performance difference between RTX3090Ti and RTX3090. In terms of configuration, it adopts i9 12900K processor, Z690 motherboard, DDR4 4000 frequency 16G*2 root (32G), 1TB M.2 NVMe pci4.0 solid state drive, and 1000W power supply.
