Introduction

The Zotac GeForce RTX 3090 Ti Amp Extreme Holo is a slick new graphics card from the house of Zotac Gaming, powered by the apex RTX 30-series GPU being debuted today. The RTX 3090 is the pinnacle of the NVIDIA "Ampere" graphics architecture, and not just maxes out all shaders physically present on the largest "GA102" silicon, but also boosts memory bandwidth and clock speeds with the idea of making this a double-digit percentage faster than the RTX 3090, the company's de facto flagship GPU until now. Its target audience is anyone who wants to play the latest games at 4K native resolution with ray tracing and maxed out details, as well as PC enthusiasts wanting to be at the top of benchmark leaderboards.



All 84 streaming multiprocessors (SM) of the GA102 silicon are enabled on the RTX 3090 Ti. This works out to 10,752 CUDA cores, 84 RT cores, and 336 Tensor cores. The memory subsystem sees an upgrade, too, with the introduction of 21 Gbps-rated GDDR6X memory chips in place of the 19.5 Gbps ones on the RTX 3090. The new chips enable a memory bandwidth of over 1 TB/s, up from the 954 GB/s on the RTX 3090. Memory size remains the same, at 24 GB. NVIDIA had gone with such a large memory amount for the original RTX 3090 because it positioned the SKU as a halo-segment product, since there's no TITAN product this generation and the large memory amount enables certain creator use-cases with large data sets.

The RTX 3090 Ti is also the first graphics card to debut the new ATX 16-pin power connector, and not just on the NVIDIA Founders Edition card, but also custom-design cards, across the board. The connector is technically capable of up to 600 W power delivery, and NVIDIA rated the typical board power of the reference RTX 3090 Ti at 450 W, which is a whole 100 W higher than the RTX 3090 and means that overclocked custom-design cards such as the Zotac Amp Extreme we're reviewing today could approach or even cross the 450 W-mark. The 16-pin connector is still very new for the PSU industry, so all board partners are required to include an NVIDIA-designed adapter that converts three 8-pin PCIe power connectors to a 16-pin connector.

The Zotac RTX 3090 Ti Amp Extreme Holo is the company's flagship air-cooled custom-design product and features an updated variant of the IceStorm 2.0 cooling solution we've seen on the likes of the RTX 3090 Amp Extreme. It features a meaty triple-slot heatsink that's ventilated by a trio of fans. There's an unmistakably large RGB lighting element along the top of the card. Underneath is a brand-new PCB with a significantly different power design built around that 16-pin connector. The PCB also features a large cutout for airflow from the cooler to pass right through. Zotac's factory-overclock for the RTX 3090 Ti is 1890 MHz boost, while the NVIDIA reference runs 1860 MHz.
