The GeForce 40 series is a family of graphics processing units developed by Nvidia, succeeding the GeForce 30 series. The series was announced on September 20, 2022, at the GPU Technology Conference (GTC) 2022 event; the RTX 4090 was released on October 12, 2022, and the RTX 4080 was released on November 16, 2022. The cards are based on the Ada Lovelace architecture and feature hardware-accelerated raytracing (RTX) with Nvidia's third-generation RT cores and fourth-generation Tensor Cores. Nvidia officially announced the RTX 4070 Ti and RTX 40 mobile series GPUs on January 3rd, 2023.

Details

Architectural highlights of the Ada Lovelace architecture include the following:

• CUDA Compute Capability 8.9
• TSMC 4N process (custom designed for Nvidia) – not to be confused with N4
• Fourth-generation Tensor Cores with FP8, FP16, bfloat16, TensorFloat-32 (TF32) and sparsity acceleration
• Third-generation Ray Tracing Cores, along with concurrent ray tracing, shading and compute
• Shader Execution Reordering (SER)
• Dual NVENC with 8K 10-bit 60FPS AV1 fixed function hardware encoding
• A new generation of Optical Flow Accelerator to aid DLSS 3.0 intermediate AI-based frame generation
• No NVLink support
• DisplayPort 1.4a and HDMI 2.1 display connections
• Double-precision (FP64) performance of the Ada Lovelace chips are 1/64 of single-precision (FP32) performance.
• All the cards feature Micron GDDR6X video memory.

1. Shader Processors : Texture mapping units : Render output units : Ray tracing cores : Tensor Cores
2. The number of Streaming multi-processors on the GPU.
3. Core boost values (if available) are stated below the base value inside brackets.
4. Pixel fillrate is calculated as the lowest of three numbers: number of ROPs multiplied by the base core clock speed, number of rasterizers multiplied by the number of fragments they can generate per rasterizer multiplied by the base core clock speed, and the number of streaming multiprocessors multiplied by the number of fragments per clock that they can output multiplied by the base clock rate.
5. Texture fillrate is calculated as the number of texture mapping units (TMUs) multiplied by the base (or boost) core clock speed.

Reception

RTX 4080

The RTX 4080 received more mixed reviews when compared to the RTX 4090. TechSpot gave the RTX 4080 score of 80/100. Antony Leather of Forbes found that the RTX 4080 consistently performed better than the RTX 3090 Ti. The GPU's power efficiency was positively received with Digital Trends finding that the GPU had an average power draw of 271W despite its rated 320W TDP.

The RTX 4080's $1199 price received criticism for its dramatic increase from that of the RTX 3080. In his review for RockPaperShotgun, James Archer wrote that the RTX 4080 "produces sizeable gains on the RTX 3080, though they're not exactly proportional to the price rise". In another critique, RockPaperShotgun highlighted that AIB models can significantly exceed the base $1199 Founders Edition price, creating further value considerations. The Asus ROG Strix AIB model they reviewed came in at $1550 which is $50 less than the RTX 4090 Founders Edition. Tom Warren of The Verge recommended waiting to see what AMD could deliver in performance and value with their RDNA 3 GPUs. AMD's direct competitor, the Radeon RX 7900 XTX, comes in at $999 compared to the $1199 price of the RTX 4080.

The RTX 4080 received criticism for reusing the RTX 4090's massive 4-slot coolers which are not required to cool the RTX 4080's 320W TDP. A smaller cooler would have been sufficient. The RTX 3080 and RTX 3080 Ti with their respective 320W and 350W TDPs maintained 2-slot coolers while the 320W RTX 4080 has a 3-slot cooler on the Founders Edition and 4-slots on many AIB models.

It was reported that RTX 4080 sales were weak compared to the RTX 4090, which had sold out during its launch a month earlier. The global cost of living crisis and the RTX 4080's generational pricing increase have been suggested as contributing factors for poor sales numbers.

RTX 4090

Upon release, the RTX 4090's performance received praise from reviewers with Tom's Hardware saying "it now ranks among the best graphics cards". A review by PC Gamer gave it 83/100, calling it "a hell of an introduction to the sort of extreme performance Ada can deliver when given a long leash". Tom Warren in a review for The Verge said that the RTX 4090 is "a beast of a graphics card that marks a new era for PC gaming". Aside from gaming performance, PCWorld's review highlighted the RTX 4090's benefits for content creators and streamers with its 24GB VRAM and AV1 encoding ability and was positive towards the Founders Edition's quiet operation and cooling ability.

However, it also received criticism for its value proposition given that it begins at $1,599. Analysis by TechSpot found that the RTX 4090's value at 1440p was worse than the RTX 3090 Ti and that the RTX 4090 did not make much sense for 1440p as it was limited by CPU bottlenecks. Power consumption was another point of criticism for the RTX 4090. The RTX 4090 has a TDP of 450W compared to the 350W of its last generation equivalent. However, Jarred Walton of Tom's Hardware noted that the RTX 4090 has the same 450W TDP as the RTX 3090 Ti while delivering much higher performance with that power consumption.

Aftermarket AIB RTX 4090 variants received criticism in particular for their massive cooler sizes with some models being 4 PCIe slots tall. This made it difficult to fit an RTX 4090 into many mainstream PC cases. YouTube reviewer JayzTwoCents showed an Asus ROG Strix RTX 4090 model being comparable in size to an entire PlayStation 5 console. Another comparison showed Nvidia's RTX 4090 Founders Edition next to the Xbox Series X for size. It was theorized that a reason for the massive coolers on some models is that the RTX 4090 was originally designed to have a TDP up to 600W before it was reduced to its official 450W TDP.
