![]() The card is much more compact than the RTX 3080, but it retains the same design language: the color scheme is predominantly black, with a matte grey finish for the outer layer. The RTX 3070 is a dual-slot card, with the dual fans sucking in air from the bottom of the case. If you care about aesthetics, the RTX 3070 Founders Edition is the card to get. The RTX 3080 introduced an innovative push-pull cooling system, and while the RTX 3070 has a traditional layout, it still manages to stand out. NVIDIA hasn't just limited the changes to the architecture it has also overhauled the design of its Founders Edition cards. The Turing SM had 64 CUDA cores for FP32 tasks and 64 INT32 cores for crunching integers, and this led to decent gains over Pascal. NVIDIA GPUs traditionally focused on either floating point or integer tasks, but with Turing, NVIDIA enabled both tasks to be performed at the same time. Without going into too much detail, what you need to know is that rasterization - the technique that GPUs leverage to render two-dimensional objects on your screen - is based on two factors, floating point (FP32) and integer (INT32) operations. NVIDIA introduced a lot of changes to the Ampere SM to eke out the gains. The GA104 silicon that powers the RTX 3070 has 46 streaming multiprocessors, which hold 128 CUDA cores each - that's how we get to the 5,888 cumulative CUDA cores for the card. ![]() The Ampere streaming multiprocessor is the key behind the performance gains with RTX 3070.īut the biggest difference is down to the streaming multiprocessor. NVIDIA made a lot of changes to achieve these gains, including overhauling the streaming multiprocessor (SM) and updating the RT cores and tweaking the Tensor cores. Thanks to the Ampere architecture, NVIDIA is touting significant gains over Turing-based RTX 20 cards.

The card has 8GB of 14Gbps GDDR6 memory over a 256-bit interface, translating to an effective bandwidth of 448GB/s. With the RTX 3070 relying on GDDR6, it misses out on these gains. GDDR6X offers higher frequencies, allowing the RTX 30 to deliver much more bandwidth than RTX 20 series cards. The RTX 3070 offers the same GDDR6 memory as its predecessor, while the RTX 30 feature the newer GDDR6X standard that NVIDIA co-created with Micron. The RTX 3070 has HDMI 2.1 and PCIe 4.0 connectivity, and is built on an 8nm node.Īs for the hardware on offer, the RTX 3070 Founders Edition features 5,888 CUDA cores along with 46 RT cores and 184 texture units, with a base clock of 1.5GHz and a boost of 1.7GHz.
