PNY GeForce RTX 4070 Ti SUPER Verto OC is an interesting custom design rendition of the new GeForce RTX 4070 Ti SUPER performance segment GPU that NVIDIA is launching this week, with sales beginning tomorrow. What makes the PNY Verto OC interesting is that it comes with factory overclocked speeds, but at the NVIDIA baseline MSRP of $800. There are other premium custom-design OC cards that we're testing, but we can't post their reviews until tomorrow. NVIDIA, over the past several recent GPU launches, has incentivized its board partners to innovate at its baseline pricing, by giving them a one day head-start with press review coverage. This ensures that they add more value to their entry-level, to make a good first impression on buyers. PNY has gone up a notch and given its card a factory OC.
The new GeForce RTX 4070 Ti SUPER is part of a mid-lifecycle refresh of the RTX 40-series Ada generation, focusing particularly on the high-end segment. The RTX 4070 Ti SUPER replaces the RTX 4070 Ti from the product stack at its $800 MSRP. You should be able to find RTX 4070 Ti cards at slightly lower prices, but the card has stopped production. The RTX 4070 Ti SUPER comes with significant improvement in specs over the original RTX 4070 Ti, with the biggest change being memory. It now gets 16 GB of memory across a 256-bit memory bus; compared to 12 GB of it across a 192-bit memory bus for the original. This change results in the engine getting fed with a 33% increase in memory bandwidth. Besides this, the card also gets a handy 10% increase in CUDA cores, and more ROPs, although the on-die cache size remains unchanged.
If you recall, NVIDIA had maxed out the AD104 silicon to create this RTX 4070 Ti, which meant that it would have to tap into the larger AD103 silicon found powering the RTX 4080 and mobile RTX 4090 series. The RTX 4070 Ti SUPER is carved out of this chip by enabling 66 out of 80 SM, worth 8,448 CUDA cores, 264 Tensor cores, 66 RT cores, and 264 TMUs. The ROP count is set at 96, out of the 112 present on the silicon. This is still 20% higher than the 80 ROPs that the RTX 4070 Ti has. The GPU runs at 2625 MHz on the PNY Verto OC (compared to 2610 MHz reference); and the memory at 21 Gbps, yielding 672 GB/s of memory bandwidth that's 33% higher than the other RTX 4070 series cards.
The new Ada Lovelace graphics architecture driving the GeForce RTX 40-series, introduces generational uplifts in performance and energy efficiency, thanks to the new 5 nm EUV foundry process, and SIMD-level innovations. The new Ada CUDA core, in addition to IPC increases and support for higher clock speeds over Ampere; features support for shader execution reordering, a feature that improves ray tracing performance. The new 3rd generation RT core supports displaced micro-meshes, a feature that increases complexity of ray traced objects without a linear increase in performance cost; and the new optical flow accelerator, a component that lets the GPU draw entire alternate frames using AI, without involving the main graphics rendering pipeline, which is needed for DLSS 3 Frame Generation to work. The company has also redesigned the memory sub-system with larger caches on the GPU, so it could narrow the memory interfaces while increasing the memory sizes.

Architecture
The Ada graphics architecture heralds the third generation of the NVIDIA RTX technology, an effort toward increasing the realism of game visuals by leveraging real-time ray tracing, without the enormous amount of compute power required to draw purely ray-traced 3D graphics. This is done by blending conventional raster graphics with ray traced elements such as reflections, lighting, and global illumination, to name a few. The 3rd generation of RTX introduces the new higher IPC "Ada" CUDA core, 3rd generation RT core, 4th generation Tensor core, and the new Optical Flow Processor, a component that plays a key role in generating new frames without involving the GPU's main graphics rendering pipeline. The GeForce Ada graphics architecture driving the RTX 4070 SUPER leverages the TSMC 5 nm EUV foundry process to increase transistor counts.
The GeForce RTX 4070 Ti SUPER gets a significant memory sub-system uplift over the original RTX 4070 Ti, besides an increase in shaders and other on-die components. Since NVIDIA maxed out the AD104 to create the RTX 4070 Ti, the only way it could go about creating the RTX 4070 Ti SUPER is by tapping into the larger AD103 that powers the RTX 4080 and the upcoming RTX 4080 SUPER. The biggest perks of the switch to AD103 is its wider 256-bit memory bus, which allowed NVIDIA to increase the memory from 12 GB to 16 GB.
The AD103 is built on the 5 nm EUV foundry process, with a die size of 379 mm² and 45.9 billion transistors. The chip features a PCI-Express 4.0 x16 host interface along with support for PCI resizable BAR; and its 256-bit wide GDDR6X memory interface. The GigaThread Engine serves as the main workflow controller for the GPU, dispatching work among the GPU's 7 graphics processing clusters (GPCs). Each GPC shares a Raster Engine and render backends among six texture processing clusters (TPCs), the indivisible subunit of the GPU. Each of these has two Streaming Multiprocessors (SM), and a Polymorph unit. Each SM contains 128 CUDA cores across four partitions. Half of these CUDA cores are pure-FP32; while the other half is capable of FP32 or INT32. The SM retains concurrent FP32+INT32 math processing capability. The SM also contains a 3rd generation RT core, four 4th generation Tensor cores, some cache memory, and four TMUs. One of the 7 GPCs on the AD103 physically only has 4 TPCs.
With a total of 40 TPCs, or 80 SM, the AD103 physically features 10,240 CUDA cores, 320 Tensor cores, 80 RT cores, and 320 TMUs; along with 64 MB of on-die L2 cache, and 112 ROPs. NVIDIA carved the RTX 4070 Ti SUPER out of the AD103 by enabling 66 out of 80 SM, 48 MB out of the 64 MB of L2 cache present; and 96 ROPs out of the 112 present. This results in 8,448 CUDA cores, 264 Tensor cores, 66 RT cores, 264 TMUs, 96 ROPs, and 48 MB of L2 cache. NVIDIA also disabled a few NVDEC units, giving this the same exact video acceleration configuration as the RTX 4070 Ti, with two NVENC and one NVDEC units. The 256-bit memory interface drives 16 GB of memory, however the memory runs at 21 Gbps, compared to the 22.5 Gbps of the RTX 4080, and 23 Gbps of the upcoming RTX 4080 SUPER. Even with 21 Gbps, the memory bandwidth on tap is an impressive 672 GB/s, a 33% increase over that of the original RTX 4070 Ti.
3rd Gen RT Core and Ray Tracing
The 3rd generation RT core accelerates the most math-intensive aspects of real-time ray tracing, including BVH traversal. Displaced micro-mesh engine is a revolutionary feature introduced with the new 3rd generation RT core. Just as mesh shaders and tessellation have had a profound impact on improving performance with complex raster geometry, allowing game developers to significantly increase geometric complexity; DMMs is a method to reduce the complexity of the bounding-volume hierarchy (BVH) data-structure, which is used to determine where a ray hits geometry. Previously, the BVH had to capture even the smallest details to properly determine the intersection point. Ada's ray tracing architecture also receives a major performance uplift from Shader Execution Reordering (SER), a software-defined feature that requires awareness from game-engines, to help the GPU reorganize and optimize worker threads associated with ray tracing.
The BVH now needn't have data for every single triangle on an object, but can represent objects with complex geometry as a coarse mesh of base triangles, which greatly simplifies the BVH data structure. A simpler BVH means less memory consumed and helps to greatly reduce ray tracing CPU load, because the CPU only has to generate a smaller structure. With older "Ampere" and "Turing" RT cores, each triangle on an object had to be sampled at high overhead, so the RT core could precisely calculate ray intersection for each triangle. With Ada, the simpler BVH, plus the displacement maps can be sent to the RT core, which is now able to figure out the exact hit point on its own. NVIDIA has seen 11:1 to 28:1 compression in total triangle counts. This reduces BVH compile times by 7.6x to over 15x, in comparison to the older RT core; and reducing its storage footprint by anywhere between 6.5 to 20 times. DMMs could reduce disk- and memory bandwidth utilization, utilization of the PCIe bus, as well as reduce CPU utilization. NVIDIA worked with Simplygon and Adobe to add DMM support for their tool chains.
Opacity Micro Meshes
Opacity Micro Meshes (OMM) is a new feature introduced with Ada to improve rasterization performance, particularly with objects that have alpha (transparency data). Most low-priority objects in a 3D scene, such as leaves on a tree, are essentially rectangles with textures on the leaves where the transparency (alpha) creates the shape of the leaf. RT cores have a hard time intersecting rays with such objects, because they're not really in the shape that they appear (they're really just rectangles with textures that give you the illusion of shape). Previous-generation RT cores had to have multiple interactions with the rendering stage to figure out the shape of a transparent object, because they couldn't test for alpha by themselves.
This has been solved by using OMMs. Just as DMMs simplify geometry by creating meshes of micro-triangles; OMMs create meshes of rectangular textures that align with parts of the texture that aren't alpha, so the RT core has a better understanding of the geometry of the object, and can correctly calculate ray intersections. This has a significant performance impact on shading performance in non-RT applications, too. Practical applications of OMMs aren't just low-priority objects such as vegetation, but also smoke-sprites and localized fog. Traditionally there was a lot of overdraw for such effects, because they layered multiple textures on top of each other, that all had to be fully processed by the shaders. Now only the non-opaque pixels get executed—OMMs provide a 30 percent speedup with graphics buffer fill-rates, and a 10 percent impact on frame-rates.
DLSS 3 Frame Generation
DLSS 3 introduces a revolutionary new feature that promises a doubling in frame-rate at comparable quality, it's called AI frame-generation. Building on DLSS 2 and its AI super-resolution (scaling up a lower-resolution frame to native resolution with minimal quality loss); DLSS 3 can generate entire frames simply using AI, without involving the graphics rendering pipeline, it's also possible to enable frame generation at native resolution without upscaling. Later in the article, we will show you DLSS 3 in action.
Every alternating frame with DLSS 3 is hence AI-generated, without being a replica of the previous rendered frame. This is possible only on the Ada graphics architecture, because of a hardware component called the optical flow accelerator (OFA), which assists in predicting what the next frame could look like, by creating what NVIDIA calls an optical flow-field. OFA ensures that the DLSS 3 algorithm isn't confused by static objects in a rapidly-changing 3D scene (such as a race sim). The process heavily relies on the performance uplift introduced by the FP8 math format of the 4th generation Tensor core. A third key ingredient of DLSS 3 is Reflex. By reducing the rendering queue to zero, Reflex plays a vital role in ensuring that latency with DLSS 3 enabled is at an acceptable level. A combination of OFA and the 4th Gen Tensor core is why the Ada architecture is required to use DLSS 3, and why it won't work on older architectures.
Packaging
The Card
The PNY RTX 4070 Ti Super Verto comes with a mostly-black color theme that has some white highlights on it from the PNY and GeForce logos. There's a cutout for air to flow through, the main cooler shroud is made from plastic while the backplate is made of metal.
Dimensions of the card are 30.5 x 12.0 cm, and it weighs 1150 g.
Installation requires three slots in your system. We measured the card's width to be 61 mm.
Display connectivity includes three standard DisplayPort 1.4a ports and one HDMI 2.1a (same as Ampere and same as non-Super Ada).
NVIDIA introduced the concept of dual NVDEC and NVENC Codecs with the Ada Lovelace architecture. This means there are two independent sets of hardware-accelerators; so you can encode and decode two streams of video in parallel or one stream at double the FPS rate. While the RTX 4070 Ti features dual units, the RTX 4070 Super and RTX 4070 come with only one of them. The new 8th Gen NVENC now accelerates AV1 encoding, besides HEVC. You also get an "optical flow accelerator" unit that is able to calculate intermediate frames for videos, to smooth playback. The same hardware unit is used for frame generation in DLSS 3.
All GeForce RTX 4070 Ti Super graphics cards use the 12+4 pin ATX 12VHPWR connector, an adapter cable is included in the box.
