Nvidia AD103: A Powerful GPU Under The GeForce RTX 4070

Nvidia AD103

Nvidia has another RTX 4070 variant brewing this one uses a down-binned AD103 GPU from the RTX 4080 Super.

AD103 vs AD104

The Nvidia GeForce RTX 4070 ranks as one of the best graphics cards for gamers. Not surprisingly, TechPowerUp seemingly has confirmation that Nvidia released a new variant of the 4070 with harvested AD103 chips, which are normally used in the faster RTX 40-series models like the RTX 4070 Ti Super, RTX 4080 (now discontinued), and RTX 4080 Super. This is strictly business as usual, making use of every possible piece of silicon by turning off non-functional portions of the chip, and we previously reported on upcoming down-binned 40-series GPUs last month.

The RTX 4070 normally utilizes the smaller AD104 die. The silicon, a product of TSMC’s 4N Finfet manufacturing process, measures 294 mm² in die size and houses up to 35.8 billion transistors. Although 60 SMs (7,680 CUDA cores) are inside the AD104 silicon, the GeForce RTX 4070 only has 46 SMs (5,888 CUDA cores) enabled. The RTX 4070 Ti (also discontinued) used the fully enabled AD104 GPU, while the RTX 4070 Super has 56 SMs (Streaming Multiprocessors) enabled.

RTX 4080 AD103

AD103 has a die size of 379 mm² and 45.9 billion transistors, meaning it’s 29% larger and thus costs 29% more to manufacture (give or take). The full chip has 80 SMs (10,240 CUDA cores), which is what Nvidia puts in the RTX 4080 Super. AD103 also supports four 64-bit memory channels (256-bit total), which are used for the 4070 Ti Super and above, while the 4070 only needs three channels (192-bit total).

There shouldn’t be any noteworthy benefit to end users in getting an RTX 4070 based on a harvested AD103 chip. Rather, it’s Nvidia likely clearing out “faulty” chips that simply couldn’t meet the required specs for the higher-end Ada Lovelace models. This follows the usual pattern with prior GPU architectures, and Nvidia has likely been collecting AD103 chips that failed to meet the requirements for at least RTX 4070 Ti Super for over a year. Now, it has enough that it’s ready to sell them off as a late-cycle update to a lower tier product and with less than 60% of the SMs enabled, this should allow the use of nearly any remaining AD103 dies.

According to Tom’s Hardware, one TechPowerUp reader reported to the news outlet that the RTX 4070 (AD103) is already on the market. At least one known MSI model, the GeForce RTX 4070 Ventus 3X E 12G OC, is already using the AD103 die. TechPowerUp’s investigation shows that the new model is already supported in the latest Nvidia 552.22 drivers.

While the AD103 chips is physically larger than AD104, the PCB design, pin map, and package are apparently the same, allowing Nvidia and its board partners to swap between the GPUs as needed. Again, this was a premeditated design decision as Nvidia knew before the first Ada Lovelace GPUs rolled off the production line that it would inevitably have some chips that would require down-binning.

AD103 Nvidia

The Nvidia Blackwell RTX 50-series graphics cards will likely hit the retail market before the end of this year, starting with the highest performance models. Nvidia will want to clear out any existing Ada Lovelace silicon as quickly as possible between now and Blackwell’s launch, and recycling dies from one SKU to another represents a good way to do that. It wouldn’t be surprising to see Nvidia also release a variant of the RTX 4070 Super using AD103 all it would need is chips with at least 56 functional SMs.

Again, this silicon swap benefits Nvidia and its partners more than the consumer. The company is unlikely to lower the RTX 4070 (AD103) pricing or anything along those lines. Consumers will still receive an RTX 4070 with the same level of expected performance though GPU temperatures could be slightly lower thanks to all the “dead silicon” in the chips.

Minor elements of the new RTX 4070 model with a down-binned AD103 GPU are carried over from its higher-end cousin, while there may be minor modifications:

RTX 4070 AD103

Greater Die: Compared to the AD104 GPU that was originally included in the RTX 4070, the AD103 GPU has a larger die size. More transistors and possibly more processing power in theory may result from this.

Similar specifications: It most likely has a memory interface width of about 192 bits and 12GB of GDDR6X memory.

Potential Core Disparity: The AD103 model may include more Streaming Multiprocessors (SMs) than the original RTX 4070 (maybe 60, similar to the RTX 4070 Ti), however some SMs may be disabled to bring the performance closer to that of the original RTX 4070.

Standard capabilities: You may anticipate capabilities like hardware ray tracing and variable-rate shading along with support for DirectX 12 Ultimate.

Important Point: Because several cores have been disabled, this variation should perform similarly to the original RTX 4070. The primary distinction is in the GPU die underneath and maybe in the number of cores.

What is big batch PCB assembly?

Big batch PCB assembly is an assembly process where you will assemble 10,000 or more PCBs in a specific period of time. The main processes you will use to assemble PCBs in large quantities are design for manufacturing and design for testing.

What are the advantages of using big batch PCB assembly? PCB assembly process

With applications in mind, big batch PCB assembly will provide you with numerous industrial and personal benefits. This is why electronic OEM prefer to use it in most of their applications.

The following are the main advantages of using mass printed circuit components:

Rapid design and prototyping process

Since you will be mass-producing or manufacturing printed circuit boards, you must assemble them uniformly. By simply creating a design and a prototype that works for each PCB, you can save a lot of time.

Short production cycle

Since the production process is fully automatic, you will also save time in the production of numerous PCBS. It all starts with the design and prototyping phase, which you'll do with the help of software and machines.

Production consistency

You will also have a very uniform production process because most of the details are predetermined before implementation. Once production begins, all manufacturing specifications will follow uniform specifications for all printed circuit boards.

Quality consistency

Since you will be producing all PCBs to similar specifications, you will automatically get consistent quality throughout the production process. In other words, you should rest easy knowing that you will have consistency across all printed boards.

First-class cost performance

It has cameras and image-processing software that can identify assembly errors and relay information for further action. It is the best tool you will use for better error detection than visual inspection.

Solder Paste Inspection (SPI)

After you have finished printing with the paste printer, you must pass it through the paste inspector. The SPI machine has a camera and communication system equipment that can examine every detail of the solder paste.It compares these details to the Gerber file and reports any kind of inconsistency.

In-Circuit Test (ICT)

In-Circuit Test, you can use the most detailed test methods to check the quality and integrity of the PCB.Here, you will have to take personal initiative and use online testing software to check the quality of your PCB.You will use the machine to detect errors in the PCB for correction.

Functional Circuit Test

Here, you will use a computer with test pins or test probes to test the functional integrity of the PCB. You can tell if the board passes the test simply by comparing the results to the design specifications.

X-ray Examination

You will use X-ray inspection to detect welding problems on the PCB that are not visible to the human eye. Here, you do not have to cut through the circuit board to see the welding quality on the printed circuit board. You'll use X-ray inspection protocols to detect errors in components and soldering on circuit boards.

Do you have a custom mass PCB assembly?

Yes, we do customize mass printed circuit boards.

You can order the most unique types of printed circuit boards and we will produce them according to your needs.

What is Rogers PCB?

Rogers PCB is a type of printed circuit board (PCB) material made from a combination of epoxy and ceramic. It is well known for its high dielectric constant, low loss tangent, and high thermal conductivity, making it an ideal material for high-frequency applications. It is used in a wide range of electronics, such as:

5G Station

Cellular Base Station Antennas and Power Amplifiers

Automotive Radar and Sensors

Microwave point to point (P2P) links

LNB’s for Direct Broadcast Satellites

Microwave equipment of all kinds.

RF Identification (RFID) Tags

Rogers PCB is produced using the raw materials of the Rogers Company. Rogers company manufactures the laminate materials that are often used for manufacturing circuit boards. The Rogers PCB is a type of high-frequency PCB board, quite different from the traditional PCB board materials, epoxy resin. It uses the ceramic base as the material of high frequency. The major advantage of Rogers PCB is the temperature stability and superior dielectric constant.

Rogers PCB has a major application in high-speed electronic designs, radio frequency applications, and commercial microwaves. The low water absorption capacity of this Rogers PCB is ideal for the application of high humidity. Other Rogers PCB applications include RF identification tags, power amplifiers, automotive radar, sensors, etc.

Rogers PCB fabrication needs in-depth research on high-frequency PCB. HITECHPCB is a Rogers PCB manufacturer and has a deep understanding of the performance of Rogers PCB material. For example, Rogers PCB laminates and Rogers PCB dielectric constant in Rogers PCB material properties Rogers PCB is a high-frequency PCB material model produced by Rogers company, different from the conventional FR-4 PCB material. There is no epoxy resin in the Rogers PCB material, and Rogers ceramic PCB is used as the High-frequency PCB material. Absorption of Rogers PCB, it can be used as an ideal choice for application ns in high humidity environments, providing customers in the high-frequency PCB industry with the highest quality.

Difference Between Rogers Materials and FR-4 Materials

By combining Rogers PCB layers with FR-4 layers, we can achieve reduced cost and maximum performance compared to if we used only Rogers layers. Thus, this process should use Rogers PCB cores instead of prepregs for this process.

FR-4 stack up with 6 layers is shown below. Because prepreg is less expensive than cores, it is placed on the outside to minimize cost. A foil build is often referred to as this.

Rogers layers are required on the outside layers, but the core is usually found on the layers that need them. Below is an example with 6 layers but with 3 cores instead of 2. This configuration is sometimes called a "core build" or "cap construction" board. Rogers PCB is a high-frequency circuit board that has ceramic laminates and reinforced hydrocarbon. A Rogers PCB may be made from cores and prepregs, but most often, the top two copper layers are carried on the core, while the rest of the board is made from standard FR-4 to reduce the cost. The PCB materials absorb the signal, due to which it has less signal loss compared to that of FR-4. At higher frequencies, the signal loss is greater in FR-4 materials. This is also the signal length and design dependent.

High-Frequency

PCB with FR-4 materials is preferred due to their low cost, reliability, and well-understood electrical and mechanical properties. They are used in various applications ranging from microwave designs to audio circuits. Unfortunately, FR-4 printed circuit boards are not suitable for high-frequency applications. Rogers created the most well-known high-frequency-special laminates. Its materials have a constant dielectric reduction of close to 20% when compared to FR-4 printed circuit boards.

The best way to determine whether your project will benefit from high-frequency laminates is to assess electrical and mechanical requirements. If you find both variations are too broad, Rogers PCB material is a better option.

Dissipation

The material used is most important when producing printed circuit boards, though it may require a high cost. However, it is not the only issue that knows the content value when it comes to the loss factor or Df. FR-4 printed circuit boards will be affected or reduced. The losses are greater when compared to printed circuit boards made from Rogers materials.

In other words, when compared to Rogers PCB, FR-4 materials have a higher dissipation factor, especially at high frequencies. Typical values for FR-4 printed circuit boards are around 0.020 and close to 0.004 for Rogers boards. Dissipation of FR-4 materials increases with frequency. High-frequency laminates primarily have a frequency-dependent stable dissipation characteristic.

The signal loss is minimized with the lower dissipation factor in FR-4. Also, the automated assembly process and the processing of FR-4 materials make them easier in the assembly and manufacturing process.

Impedance Stability

Impedance is the measure of the current opposition when applying voltage. In many design applications, the stable impedance is essential and is an area where the materials like Rogers and FR-4 are applied.

FR-4, despite its low cost, is prone to high variations in the dielectric constant with the change in temperature across the length and width of the substrate. In terms of impedance stability, Rogers' material has a wider range of dielectric constants than FR-4 content.

High-frequency laminates are preferable for circuits that require little variation over wide temperature ranges. In this case, you may need to use printed circuit boards made of Rogers materials rather than FR-4 materials, especially if most of your operations involve working in high-temperature environments.

Dielectric Constant

The dielectric constant of any material measures a substance's ability to store some electrical energy across an electrical field. When it comes to dielectric constant, FR-4 has a dielectric constant of about 4.5, which is much lower than Roger's material, which has a dielectric constant of about 6.15 to 11.

The dielectric constant of FR-4 is comparatively higher than that of plastic materials. Using FR-4 materials can save at least 25% of PCB made from such materials. Other factors that make FR-4 articles available include their lightweight, moisture resistance, and high dielectric strength. Even though the Rogers PCB has a higher dielectric than FR-4, you can go with FR-4. FR-4 and Rogers 4350b and 4350 are similar manufacturing processes, although FR-4 stores electrical energy effectively.

Thus, PCB with higher dialect trends breaks easier when subjected to intense electric fields.
