NVIDIA RTX 2000 Ada vs RTX 2000E Ada: dual slot at 70 W or single slot at 50 W

The difference between the RTX 2000 Ada and the RTX 2000E Ada

The NVIDIA RTX 2000 Ada Generation and the NVIDIA RTX 2000E Ada Generation share their memory and their core counts: 16 GB of GDDR6 with ECC at 224 GB/s and 2,816 CUDA cores. They differ in the power limit, the cooler and the slot width. The RTX 2000 Ada takes two slots and 70 W and is listed at 12.0 TFLOPS in single precision; the RTX 2000E Ada takes one slot and 50 W and is listed at 8.9 TFLOPS. The free slot and the power budget of the system decide between them, and we supply both.

NVIDIA datasheets 2999417 (January 2024) for the RTX 2000 Ada and 4328932 (October 2025) for the RTX 2000E Ada; the power-cable row comes from NVIDIA's quick start guide for the RTX Ada cards and from Lenovo's product guide LP2207 for the 2000E (updated 6 October 2025).

What the two cards have in common

In nine of the thirteen rows the two cards agree; on the power cable they agree in substance, and only the document behind the row differs. Both cards belong to the Ada Lovelace generation and carry the same amount of memory on the same 128-bit interface, so a model, a scene or a texture set that fits one fits the other. Both connect over PCIe 4.0 with eight lanes on what NVIDIA's footnotes call a full-length interface. Both have four Mini DisplayPort 1.4a outputs with the same display lines, which allow up to four displays at 4096 × 2160 and 120 Hz or at 5120 × 2880 and 60 Hz, and two at 7680 × 4320 and 60 Hz. Both have one encoder and one decoder with AV1 in both directions, and neither has an HDMI output.

NVIDIA's driver lists show how close the two cards are. The Linux list gives both the PCI device ID 28B0 and tells them apart by the subsystem ID, 1870 for the RTX 2000 Ada and 1871 for the 2000E. The release notes of the current RTX Enterprise drivers 621.14, 597.30 and 582.99 list each card under its own name, so one driver package serves a fleet that mixes them.

70 W against 50 W in NVIDIA's performance rows

With the same number of cores, the lower power limit shows in the two rate rows of the datasheets. By our arithmetic the 2000E reaches 74 per cent of the RTX 2000 Ada's figure in single precision (8.9 against 12.0 TFLOPS) and 74 per cent for ray tracing (20.5 against 27.7 TFLOPS), at 71 per cent of the board power. Both sheets footnote the single-precision figure as a peak rate based on the GPU boost clock.

That ratio is the only published relation between the two cards. For the RTX 2000 Ada measurements exist: SPEC's results summary for SPECapc for SolidWorks 2024, updated on 26 November 2024, lists an HP Z2 Mini G9 with a Core i7-14700 and this card at a GPU composite of 4.12 with full-scene anti-aliasing and 4.71 without, at Full HD; Blender Open Data, read 10 November 2026, shows a median of 2,658.83 samples per minute over 25 submissions with Blender 4.5.0, in a crowd-sourced database. For the RTX 2000E Ada we know of no review or benchmark that names its system, date and conditions. How far the datasheet ratio carries over to an application is therefore not documented, and we print no percentage for it.

The AI rows cannot be set against each other at all. The RTX 2000 Ada datasheet gives a Tensor figure of 191.9 TFLOPS, an effective FP8 rate that assumes sparsity. For the 2000E two editions of the datasheet give different AI TOPS values, and we print neither.

Two slots or one in the same outline

Both boards are 2.7 in high and 6.6 in long, about 69 by 168 mm by our conversion; NVIDIA itself publishes neither millimetres nor a weight for either card. 2.7 in is half-height, the format usually called low profile. The difference is the width: the RTX 2000 Ada occupies two slot positions, the 2000E one. Both datasheets call the thermal solution active, so each card has its own fan; on the 2000E the cooler of single width comes with the lower power limit.

A small-form-factor workstation with two free slot widths takes the RTX 2000 Ada, the card with the higher datasheet rates. A compact industrial computer, an edge box or a rack system with one free slot width takes the 2000E only. We supply both cards across the EU; send us the chassis model and the number of free slots and we reply with the card that fits and a written quote within one business day. The other single-slot boards are in our comparison of single-slot NVIDIA RTX cards, and all half-height boards in the comparison of low-profile NVIDIA RTX cards.

Neither card uses a power cable, and the sources differ

The RTX 2000 Ada datasheet gives 70 W of total board power, and NVIDIA's quick start guide for the RTX Ada cards says that this card does not use a power cable. The 2000E datasheet gives 50 W and has no row for a power connector; the statement that it does not require an auxiliary power cable is Lenovo's, from its product guide for the card. NVIDIA's power guidelines for workstation products of July 2023 name 75 W as the typical rating of a PCIe slot. The document has no row for the RTX 2000 Ada, and the figure is a general reference point, no statement about a particular mainboard; what the slot of a given system supplies is for its maker to state.

NVIDIA publishes a power-supply wattage for neither card. In a system that is already close to the limit of its supply, the 20 W between the two cards can decide; in a workstation with reserve it does not.

Mosaic footnotes and the video support matrix

Both datasheets list NVIDIA Mosaic, with different footnotes. The RTX 2000 Ada footnote names Windows 10, Windows 11 and Linux and adds that the configuration offers neither frame-lock synchronisation nor display overlap. The 2000E footnote reads "Windows 10 and Linux". Neither card is on NVIDIA's RTX PRO Sync page of 15 October 2026, so either is planned as one card with up to four displays. The 2000E datasheet also lists HDCP 2.2.

For video, NVIDIA's Video Encode and Decode GPU Support Matrix of 16 October 2026 has a row for the RTX 2000 Ada: one encoder, an unrestricted number of concurrent sessions, AV1 encoding, no 4:2:2 encoding. The matrix has no row for the 2000E. Its datasheet states one encoder and one decoder with AV1, and the session limit is not published.

What NVIDIA and software makers publish for each card

NVIDIA blog of 12 February 2024; NVIDIA's "CUDA GPU Compute Capability" page and Video Encode and Decode GPU Support Matrix (both 16 October 2026), MIG User Guide (4 November 2026), vGPU supported-GPU list (2 October 2026), RTX Enterprise release notes 621.14 (4 November 2026) and "Compare Professional Laptop GPUs" page; Dassault's SOLIDWORKS 2026 certification list and the list of supported GPUs of D5 Render 3.1, read 10 November 2026.

The table shows a difference that no datasheet row contains. The RTX 2000 Ada is documented far more widely. In Dassault's list a row stands for one computer model with one card and one driver. For the RTX 2000 Ada the list has rows for, among others, the Lenovo ThinkStation P3 Ultra Gen 2 and the HP Z2 Mini G1i, and it holds laptop rows under the same card name. For the 2000E there is no entry. That means no row has been published; it is no statement that the software fails on the card.

The compute capability matters to AI software. NVIDIA's page gives the RTX 2000 Ada 8.9, the level that NVIDIA's NIM support matrix for visual generative AI of 20 October 2026 requires for FP8, and it does not name the 2000E. By its name the 2000E is an Ada generation card; a stack that checks for a stated capability should be confirmed on the card itself. By memory the same model files fit both cards, and our article on local LLMs on 16 GB cards lists them.

RTX 2000E Ada vs RTX A2000 and RTX A1000

Two older and smaller cards come up in the same searches, the RTX A2000, whose outline and power the RTX 2000 Ada shares, and the RTX A1000, whose slot width and power the 2000E shares.

NVIDIA datasheets: RTX A2000 (1987439, August 2021 and May 2022), RTX A1000 (April 2024), RTX 2000E Ada Generation (4328932, October 2025), RTX 2000 Ada Generation (2999417, January 2024). For the RTX A2000 the datasheet gives 8.0 TFLOPS and NVIDIA's line cards of November 2022 and March 2023 give 7.9.

RTX A2000. The Ampere card has the same 2.7 by 6.6 in outline in two slots and the same 70 W without a cable as the RTX 2000 Ada. Against it the 2000E offers 16 GB in place of 6 or 12 GB, AV1 encoding where the RTX A2000 decodes AV1 only, and a single-precision figure of 8.9 against 8.0 TFLOPS, in half the slot width and with 20 W less. Two rows go the other way: the RTX A2000 has the higher memory bandwidth, 288 against 224 GB/s, and a PCIe 4.0 x16 link. Its 3,328 CUDA cores cannot be set against the 2,816 of the Ada cards, because core counts compare only within one generation. NVIDIA's own speed statement concerns the dual-slot card: its blog of 12 February 2024 states up to 1.5 times the performance of the previous-generation RTX A2000 12GB in professional workflows for the RTX 2000 Ada, without publishing test conditions. No such statement exists for the 2000E. The upgrade from the RTX A2000 is the subject of our comparison RTX 2000 Ada vs RTX A2000.

RTX A1000. The NVIDIA RTX A1000 is the 8 GB card for the same single slot and the same 50 W; it is 6.4 in long. The 2000E doubles the memory, adds ECC, which NVIDIA does not state for the RTX A1000, and encodes AV1, which the RTX A1000 does not. The RTX A1000 has two decoders against one, a limit of 8 concurrent NVENC sessions in NVIDIA's matrix, and its 8K display line ends at 30 Hz against 60 Hz. Where 8 GB is enough, the RTX A1000 is the card to order; its figures are in the RTX A1000 specs, and the order is described on the page to buy the RTX A1000. The step from 8 GB to 16 GB is worked through in RTX A1000 vs RTX 2000 Ada and RTX PRO 2000.

Which card for which system

• Small-form-factor workstation with two free slot widths. The RTX 2000 Ada: the higher rates, a product page and the wider documentation. Details are in its specs and on the page to buy the RTX 2000 Ada.
• CAD seat that has to match a software maker's list. The RTX 2000 Ada, checked against the row for the workstation model in question.
• System with one free slot width or a fixed 50 W budget. The RTX 2000E Ada; see its specs and the page to buy the RTX 2000E Ada. What its 16 GB carry in an inference system is covered in our article on the RTX 2000E Ada for edge AI.
• One slot, and 8 GB is enough. The RTX A1000.
• New seats with two slot widths and no tie to an Ada image. The NVIDIA RTX PRO 2000 Blackwell has 16 GB of GDDR7 at 288 GB/s and 17 TFLOPS in single precision at the same 70 W in two slots; see the specs of the RTX PRO 2000 Blackwell and the page to buy it. Our existing comparison RTX PRO 2000 vs RTX 2000 Ada covers that generation step.
