NVIDIA GeForce RTX 2080 Ti (Desktop) vs NVIDIA RTX A5000 Laptop GPU vs NVIDIA GeForce RTX 2080 Super Max-Q

The NVIDIA GeForce RTX 2080 Ti is the fastest consumer desktop graphics card in 2018 and the fastest Turing RTX card at launch. It offers 4,352 shaders, 11 GB GDDR6 with a 352 bit interface (14 GHz, 616 GB/s for the Founders Edition). Furthermore, the 2080Ti includes 544 Tensor cores and 68 raytracing cores.

Features

NVIDIA manufacturers the TU102 chip on a 12 nm FinFET process and includes features like Deep Learning Super Sampling (DLSS) and Real-Time Ray Tracing (RTRT), which should combine to create more realistic lighting effects than older GPUs based on the company's Pascal architecture (if the games supports it). The RTX 2080 Ti is also DisplayPort 1.4 ready, while there is also support for HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) and H.265 video en/decoding (PlayReady 3.0).

Performance

The gaming performance of the 2080 Ti is around 27% faster than a RTX 2080 in 4K and around 35% faster than a GTX 1080 Ti. Therefore, the 2080 Ti is capable of max settings in 4K for all current AAA games. Adding raytracing may however reduce the performance below 60 fps.

Power Requirements

NVIDIA estimates that the RTX 2080 Ti should consume a maximum of 250 W or 260 W for the Founders Edition, which is  on a level with the GTX 1080 Ti (250 Watt).

The NVIDIA RTX A5000 Laptop GPU or A5000 Mobile is a professional graphics card for mobile workstations. It is based on the GA104 Ampere chip and similar to the consumer GeForce RTX 3080 Laptop GPU. It offers the same 6.144 graphics cores, 48 RT cores, 192 Tensor cores and 16 GB GDDR6 graphics memory with a 256 Bit memory bus. It supports PCIe 4.0 and will be available in different variants from 80 - 165 Watt (TGP) with different clock speeds (and performance). The GPU supports eDP 1.4b to connect the internal monitor and DisplayPort 1.4 and HDMI 2.1 for external connections.

There is no more Max-Q variant (formerly used for the low power variants) but every OEM can choose to implement Max-Q technologies (Dynamic Boost, Whispermode).

The raw performance should be similar to the GeForce RTX 3080 for laptops at the same TGP level. Both GPUs depend heavily on good cooling and a high TGP for good performance. At a similar power consumption level the RTX A5000 should be clearly faster than the old Quadro RTX 5000 and 5000 Max-Q. The desktop variant of the A5000 however, is a lot faster.

The GA104 chip offers 6,144 FP32 ALUs of which half can also execute INT32 instructions (i.e. 3,072 INT32 ALUs). With Turing all shaders could still execute FP32 or INT32 instructions. The raytracing and tensor cores on the chip were also improved according to Nvidia. The Ampere chips also include an improved 5th generation video encoder (NVENC for H.264 and H.265) and a 7th generation decoder (for various formats now including AV1).

The GA104 chip is manufactured by Samsung in 8nm (8N), which is not quite able to keep up with the 7nm node at TSMC (e.g. used by AMD and also for the professional GA100 Ampere chip).

The NVIDIA GeForce RTX 2080 Super with Max-Q design is the power saving variant of the mobile GeForce RTX 2080 Super with reduced clock speeds, performance and of course power consumption. It is intended for thin gaming laptops and based on the same TU104 chip with 3,072 shaders, 8 GB GDDR6 memory and a 256 Bit memory bus.

Currently it looks like there are three variants with a TGP of 80, 85 and 90 Watt. The clock speed ranges from 735 - 975 MHz for the base clock speed and 1080 - 1230 for the boost.

With the refresh, Nvidia also reworked the Max-Q technologies for more efficiency. Low Voltage GDDR6 (lower clocked but more headroom for the GPU) and improved regulator efficiency should improve the performance per Watt. Two new optional features can also be implemented by the OEM. Max-Q Dynamic Boost is able to shift power from the CPU to the GPU on a per frame basis to increase overall performance. Furthermore, the laptop manufacturer can also implement Advanced Optimus with a dynamic display switch (hardware) to enable Optimus, G-SYNC and high refresh rate displays (up to 4K 120 Hz).

Features

NVIDIA manufacturers the TU104 chip on a 12 nm FinFET process and includes features like Deep Learning Super Sampling (DLSS) and Real-Time Ray Tracing (RTRT), which should combine to create more realistic lighting effects than older GPUs based on the company's Pascal architecture (if the games supports it). The RTX 2080 Super Max-Q is also DisplayPort 1.4 ready, while there is also support for HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) and H.265 video en/decoding (PlayReady 3.0).

Performance

Due to the lower clock rates, the Max-Q variant is clearly slower than the mobile RTX 2080 Super. In our benchmarks with the first devices, the performance is very similar to the old RTX 2080 Max-Q and only on a level with the non Max-Q RTX 2070. Therefore, the performance is ideal for 1440p gaming at max details for demanding games like Red Dead Redemption 2, Control or Borderlands 3. Less demanding games like F1 2019 can be played in 4k with maximum settings. Detailed gaming benchmarks can be found at the end of this page.

The power consumption of the card is between 80 - 90 Watt TGP and therefore significantly lower than the RTX 2080 Super Mobile (150 - 200 Watt).
