The Nvidia cards here also support DLSS 2.0 (Deep Learning Super Sampling) and Nvidia Reflex. RTX 3090 is the only card here that includes SLI multi-GPU support using the NVIDIA RTX NVLink Bridge. Other salient features include PCI Express 4.0, Real-Time Ray Tracing, HDMI 2.1, AV1 decode, and Microsoft DirectStorage API. The cards also support variable refresh rate technologies (G-Sync/FreeSync) to reduce stuttering in games for a smoother gaming experience. RTX 3080 has the lowest amount of memory here which is 10GB GDDR6X and its runs at 19Gbps delivering a memory bandwidth of 760 GB/s.Īll these cards are loaded with the latest features and support the latest graphics APIs that include DirectX 12 Ultimate, and OpenGL 4.6. RTX 3080 Ti has got 12GB GDDR6X memory which is half of what is present in the RTX 3090 and it runs at a slightly slower speed of 19GB/s and delivers a memory bandwidth of 912 GB/s. However, RX 6900 XT comes with a 128MB ultra-high-speed memory cache called Infinity Cache that helps the card in achieving peak memory bandwidth of up to 1664 GB/s (3.25x effective bandwidth). It comes with 16GB GDDR6 memory that runs at 16Gbps and delivers effective memory bandwidth of 512 GB/s.

The card with the second-highest memory is the Radeon RX 6900 XT.

Here, RTX 3090 has the highest and fastest memory which is 24GB GDDR6X running at 19.5 Gbps and delivering a bandwidth of 936 GB/s. RTX 3080 Ti, RTX 3090, and RTX 3080 all come with GDDR6X memory but in different capacities and configurations. Must Read: CUDA Cores vs Stream Processors Difference Explained However, due to the smaller 7nm fabrication process, RX 6900 XT is quite a power-efficient card given the performance it offers. You must note that you cannot compare CUDA Cores and Stream Processors based on their numbers as it would be like comparing apples to oranges. The card comes with 5120 Stream Processors, and 80 Ray Accelerators / RT Cores but it does not have any Tensor Cores or its equivalent cores. It uses Navi 21 GPU which is built on the 7nm fabrication process. Radeon RX 6900 XT is an AMD graphics card that uses the RDNA 2 GPU architecture which is way different from Ampere architecture. RT Cores are used for Real-Time Ray Tracing and Tensor Cores are used for DLSS and AI processing in supported games and applications. On the other hand, RTX 3080 has the lowest Core count as it comes with 8704 CUDA Cores, 68 RT Cores, and 72 Tensor Cores. RTX 3080 Ti uses slightly lesser Cores than RTX 3090 and has got 10240 CUDA Cores, 80 RT Cores, and 320 Tensor Cores. The card with the highest number of Cores is the RTX 3090 and it comes with 10496 CUDA Cores, 82 RT Cores, and 328 Tensor Cores. All these graphics cards use GA102 GPU chip where the RTX 3090 comes with a fully unlocked GA102 chip while RTX 3080 Ti and RTX 3080 use a cut-down version of the GA102 chip.
#Rtx 3090 power consumption series
RTX 3080 Ti, RTX 3090, and RTX 3080 belong to the GeForce RTX 30 series and use Ampere GPU architecture built on the 8nm fabrication process. Here is the comparison between RTX 3080 Ti, RTX 3090, RTX 3080, and RX 6900 XT graphics cards based on their specifications, performance, pricing, power consumption, and features. RTX 3080 Ti vs RTX 3090 vs RTX 3080 vs RX 6900 XT Comparison So, if you want to know how RTX 3080 Ti stands against the RTX 3090, RTX 3080, and RX 6900 XT in major departments then here I am going to compare them taking into account all the important parameters so that you can decide whether you should go for it or not. The card is facing a lot of criticism from the gaming and tech community because of its very aggressive pricing compared to the performance it offers to its major competitors. RTX 3080 Ti comes with lots of features and offers great 1440p and 4K gaming performance but when it comes to pricing then RTX 3080 Ti is way more expensive than RTX 3080 and RX 6900 XT but is somewhat cheaper than RTX 3090. The major competitors of the RTX 3080 Ti are the RTX 3090 and AMD Radeon RX 6900 XT. It is now the second most powerful graphics card in the GeForce RTX 30 series, pushing RTX 3080 to the third spot. The release of RTX 3080 Ti in the Nvidia RTX 30 series has made the high-end graphics card market quite interesting. Thank you for supporting the work I put into this site!)
