NVIDIA GeForce RTX 4080 16 GB “Ada” Founders Edition Review – What The Price?

NVIDIA GeForce RTX 40 Series - GeForce RTX 4080

The NVIDIA GeForce RTX 4080 will use 76 SMs of the 84 SMs for a total of 9728 CUDA cores. The GPU will come packed with 64 MB of L2 cache and a total of 112 ROPs which is simply insane. The clock speeds for the graphics card are rated at 2210 MHz base and 2510 MHz boost clocks and we have already seen over 3 GHz speeds with overclocking which you can read more about here.

As for memory specs, the GeForce RTX 4080 features 16 GB GDDR6X capacities that will be adjusted at 22.5 Gbps speeds across a 256-bit bus interface. This will provide up to 720 GB/s of bandwidth. This is still a tad bit slower than the 760 GB/s bandwidth offered by the RTX 3080 since it comes with a 320-bit interface but a lowly 10 GB capacity. To compensate for the lower bandwidth, NVIDIA could be integrating a next-gen memory compression suite to make up for the 256-bit interface.

• NVIDIA GeForce RTX 4080 16 GB "Official" TBP - 320W
• NVIDIA GeForce RTX 3080 12 GB "Official" TBP - 350W

As far as the power consumption is concerned, the TBP is rated at 320W. The card will be powered by a single 16-pin connector which delivers up to 600W of power. Custom models will be offering higher TBP targets.

NVIDIA GeForce RTX 4080 Graphics Cards Performance

As for the performance of these monster GPUs, NVIDIA shared the computational and gaming performance figures and it looks like the GeForce RTX 4080 will be sitting slightly ahead of the GeForce RTX 3090 Ti with around 50 TFLOPs of Compute power.

Just for comparison's sake:

• NVIDIA GeForce RTX 4090: 83 TFLOPs (FP32) (2.5 GHz Boost clock)
• NVIDIA GeForce RTX 4080: 49 TFLOPs (FP32) (2.5 GHz Boost clock)
• NVIDIA GeForce RTX 3090 Ti: 49 TFLOPs (FP32) (1.86 GHz Boost clock)
• NVIDIA GeForce RTX 3090: 36 TFLOPs (FP32) (1.69 GHz Boost clock)

Based on a boost clock speed of 2.5 GHz, you get up to 49TFLOPs of compute performance and you can definitely squeeze out a lot more with an overclock as we had demonstrated with the RTX 4090. One should remember that compute performance doesn't necessarily indicate the overall gaming performance. Even so, it will be a huge upgrade for gaming PCs and an 8.5x increase over the current fastest console, the Xbox Series X.

This will be a 2x compute performance uplift and a 2x gain in gaming performance as NVIDIA has demonstrated for each graphics card versus its predecessor and this is without even factoring in the RT and Tensor core performance which are expected to get major lifts too in their respective department.  A 2-4x gain over the RTX 3090 & RTX 3090 Ti would be very disruptive.

Gamers should expect 4K gaming to be buttery smooth on these graphics cards and with DLSS, we might even see playable 60 FPS at 8K resolution which is something that NVIDIA has been trying to achieve with its RTX 3090 series BFGPUs for a while now.

NVIDIA GeForce RTX 4080 Graphics Cards Price & Availability

The NVIDIA GeForce RTX 4080 16 GB graphics card will be available starting tomorrow for a price of $1199 US. The card will be available in both Founders Edition and custom graphics card flavors at launch.

NVIDIA Founders Edition is Designed To Utilize Up To 600W of Power For Higher Overclocking

As for its brand new Founders Edition cards, the GeForce RTX 4090 24 GB and RTX 4080 16 GB, NVIDIA has produced a compact PCB similar to the ones we saw on the previous generation & designing a PCB like this helps improve airflow and cooling performance.

NVIDIA says that they have further optimized the Dual Axial Flow Through system, increasing fan sizes and fin volume by 10%, offering 20% higher airflow and upgrading to a 23-phase power supply (20+3 Phase for RTX 4090). Memory temperatures are reduced, and the new, substantially more powerful Ada GPUs are kept cool in ventilated cases, giving gamers excellent overclocking headroom. NVIDIA went through a rigorous testing procedure and is said to have evaluated as many as 50 fan designs before finalizing the one we are getting on the new cards. The cooler is used to dissipate heat from the heatsink assembly that comprises a vapor chamber, a big jump from the previous design too.

The NVIDIA GeForce RTX 4080 also uses the same cooler as the RTX 4090 Founders Edition and since it has a lower TDP, it should deliver even better thermal performance.

Each GeForce RTX 40 Series Founders Edition graphics card reduces cable clutter by leveraging the new standard GPU power input of next-gen ATX 3.0 power supplies, the PCIe Gen-5 16-pin Connector. This enables you to power GeForce RTX 40 Series graphics cards with just a single cable, improving the aesthetics of your build. If you are using a previous-gen power supply, an adapter cable is included in the box, allowing you to plug in three 8-pin power connectors, with an optional fourth connector for more overclocking headroom. ATX 3.0 power supplies will be available in October from ASUS, Cooler Master, FSP, Gigabyte, iBuyPower, MSI, and ThermalTake, with more models to come.

One advantage of the new 16-pin connector is that while the Founders Edition cards are designed at 450W & 320W, respectively, they can utilize the extra headroom provided through the new connector for extreme overclocking with the RTX 4090 going for that full 600W mark. The new power delivery also gives the RTX 40 series a 10x increase in response time to power transient management compared to the previous generation.

The new cards also feature DP 1.4a (4K 12-bit HDR @ 240Hz) and HDMI 2.1 (4K 120Hz HDR / 8K 60Hz HDR). All cards are compliant with the PCIe Gen 4 interface on existing motherboards and also feature full compliance with the Resizable-BAR technologies.

Next-Gen Micron GDDR6X Dies Run 10C Cooler Thanks To New Process Node

NVIDIA has also leveraged Micron's latest GDDR6X memory chips for its GeForce RTX 40 graphics cards which run 10C cooler, are more power efficient and since they are all 16Gb DRAM dies, they can be fused on one side of the PCB to be cooled better than dual-sided memory.
