Nvidia RTX 50 Series: News, rumors & more
DexertoLooking for the latest on the Nvidia RTX 50 series graphics cards? While the GPUs remain elusive, leaks and rumors point to another generational leap in performance.
The RTX 50 series of GPUs is inevitably coming. The ‘Blackwell’ architecture was announced at GTC 2024, though only the Enterprise-focussed version so far.
As a result. much of the information remains speculative, since it relies on leaks provided by industry insiders Kopite7Kimi and Moore’s Law is Dead. Those two have had a relatively good accuracy rate in the past. But, until Team Green officially releases the specifications of the new GPUs, all of this must be taken with a pinch of salt.
RTX 50 series specifications speculation
The Blackwell architecture has been officially announced by Nvidia at GTC 2024. Though the chips are not the same as commercial gaming GPUs, the specs do at least provide some helpful information. When combined with the latest leaks from Kopite7Kimi, it’s suggested that the flagship gaming GPU chip, the GB202, will use the same process node as the AI-focussed GB101 chip.
It is also expected that Nvidia will offer significant advances in performance, with the flagship GB202 gaming chip having considerable improvements compared to the Ada Lovelace AD102 chips. In particular, the L1 cache will see some large gains in performance.
Kopite7Kimi indicated (via WCCFTech) that the chip would offer 12 GPCs, with 8 TPCs each, providing a total of 96 TPCs. Using the Ada Lovelace structure as a template would give us 192 SMs, which equates to a massive 24,567 CUDA cores. That is an increase of 33% over the Ada equivalent AD102 chip.
GPU chip | GB202 (Blackwell) | AD102 (Ada Lovelace) |
CUDA cores | 24,567 | 18,432 |
Memory cap | 48 GB | 24 GB |
Max memory bus | 512-bit | 384-bit |
Memory technology | GDDR7 | GDDR6X |
Earlier leaks from Kopite7Kimi pointed towards Nvidia reusing the 384-bit memory bus from the Ada chips for the Blackwell chips, instead of upgrading to 512-bit. However, a May report says Nvidia will be upgrading to a 512-bit memory bus, at least on its flagship chips.
According to Moore’s Law is Dead, the uplift in performance from the 40 series to the 50 series will not be as impressive as other generations.
Blackwell GPU die breakdown speculation
Die | Potential GPU |
GB202 | RTX 5090 / Blackwell Titan |
GB203 | RTX 5080 |
GB205 | RTX 5070 Ti / RTX 5070 |
GB206 | RTX 5060 Ti / RTX 5060 / RTX 5050 Ti |
GB207 | RTX 5050 / RTX 5030 |
The chips are expected to be cut down into five different dies: GB202, GB203, GB205, GB206, and GB207. The GB202 is the flagship, and the GB207 is reserved for the budget end of the range. Curiously, the GB204 is missing from the lineup. Historically, 204 chips have powered the popular 70-suffix cards.
As of September 2024, Benchlife has confirmed that it knows of five RTX 50-series card designs currently in progress, matching up to the five chips we are aware of.
According to Kopite7Kimi, the GB203 chip will be ‘half of GB202’, which would match the difference in performance between the RTX 4090 and the RTX 4080. Based on this, and following the trends set by the 40 series.
It is unknown if Nvidia plans to keep the monolithic structure for its next generation of gaming GPUs or utilize the MCM or multi-chip-module structure. AMD is reportedly already experimenting with chiplet configurations with its Radeon graphics cards, and many analysts expect that this is the direction GPU development needs to head to maintain improvements in successive generations.
A leak from RedGamingTech, which Kopite7Kimi later confirmed, suggested that Nvidia was developing a new Titan card using the Blackwell architecture. This would use the GB202 graphical processor and could deliver up to 15% higher performance than the RTX 5090. It is unknown at this stage if this card would make it to the consumer market.
As usual, until the specifications are officially revealed, all this needs to be taken with a healthy dose of skepticism.
RTX 50 memory configuration
Once again, Kopite7Kimi is the information source regarding the memory configuration for the RTX 50 series. This leak included the bit width for the memory bus, along with the configuration and memory type.
Processor | Config | Bus Bit width | Memory type |
GB202 | 12 x 8 | 512-bit | GDDR7 |
GB203 | 7 x 6 | 256-bit | GDDR7 |
GB205 | 5 x 5 | 192-bit | GDDR7 |
GB206 | 3 x 6 | 128-bit | GDDR7 |
GB207 | 2 x 5 | 128-bit | GDDR6 |
As mentioned above, the GB202 is believed to be the processor that will power the flagship RTX 5090, which reinforces the likelihood that it will have the 512-bit memory bus leaked previously.
One surprise is the GB207, believed to be powering the RTX 5060. The 60-suffix cards have always been a popular option for consumers, but it seems that the GB207 will strongly resemble the AD106 from the current generation RTX 4060, not even upgrading to GGDR7 RAM.
Wattage claims
In mid-July 2024, Everest on Twitter/X noticed that an online tool called the Seasonic PSU Wattage calculator had been updated to include data from the RTX 50 series of desktop graphics cards. This data may not be completely accurate but it provides some interesting information, especially since it includes the RTX 5050.
GPU | TDP (W) |
RTX 5090 | 500 |
RTX 5080 | 350 |
RTX 5070 | 220 |
RTX 5060 | 170 |
RTX 5050 | 100 |
Data posted by Benchlife as of September 2024 suggests that the RTX 5090 will actually consume 550W of power, with the RTX 5080 being considerably less of a power hog at a more modest 350W.
Kopite7Kimi disputes these figures, however. Instead pointing towards the RTX 5080 being a 400W card, with the RTX 5090 at an eye-watering 600W.
However, Kopite7Kimi did not clarify if these figures represented Total Graphical Power (TDP), or Thermal Design Power (TDP), which is an important distinction when it comes to graphics cards.
Benchlife responded to Kimi’s information saying that the 600W figure would refer to the heat dissipation capacity of the special high-wattage cooling module for the RTX 5090.
RTX 50 series features speculation
Thanks to information once again courtesy of persistent leaker Kopite7Kimi, we can expect that the RTX 50 series of graphics cards will feature support for Display Port 2.1, along with HDMI 2.1. An update compared to the Ada Lovelace series, which did not feature DisplayPort 2.1 support.
The power connector has proved to be something of a contentious subject. After reports of the 12VHPWR connector found on the RTX 4090 and the 40 Super cards melting under some circumstances, many consumers were hoping a change was forthcoming from Team Green.
Moore’s Law Is Dead recently revealed that Nvidia plans to switch to an entirely new connector type for its next-generation cards. The leak suggests that Nvidia is working on an all-new 16-pin connector, but this has not yet been substantiated by other sources.
If Nvidia sticks with the 12VHPWR connector then the power draw would be limited to 600W, though rumors that Nvidia plans on touting the efficiency of its new cards suggest it will be considerably under this limit.
RTX 50 series release date speculation
A new post on X/Twitter from Kopite has indicated that the 50-series might not debut until CES 2025. That would put a severe dent in any hopes of seeing a 2024 release.
However, prior leaks courtesy of Moore’s Law is Dead suggest that the first card in the RTX 50 series could be launched as soon as Q4 of 2024. If these rumours are accurate the first of the Blackwell gaming GPUs to see retail will be the RTX 5090.
The unnamed source told Moore’s Law is Dead that the launch date will depend on the sales of the existing 40 series cards, particularly the refreshed 40 Super cards. The source goes on to state that Nvidia plans to promote the improved efficiency of the 50 series at CES 2025, with a launch to coincide.
Kopite7Kimi returned with a prediction that the RTX 50 series would not hit store shelves until 2025. Tech outlet RedGamingTech also reiterated that Q4 2024 was the original release date, but some sort of issue has pushed back the launch. No reason has been directly identified behind the possible delay, though some commentators are pointing toward a GDDR7 supply problem.
RTX 50 series price rumours
Very little information is available on even tentative pricing for the Blackwell 50 series at this point. The best estimate for pricing is that the RTX 5090 will retail with an MSRP of $1699 at launch.
Nvidia is said to have spent an eye-watering $10 billion on developing the Blackwell platform, though it is expected that the company will attempt to recoup much of that cost through sales of its dedicated AI chips.
It does leave many analysts and consumers worried about what price structure Team Green will use for the 50 series. Especially since high demand sent the RTX 4090 much higher than its launch price of $1,600 and far into the $2,000 range.
However, the 40 Super refresh cards adopted a fairly aggressive price strategy in an effort to keep pace with AMD. Only time will tell which stance Nvidia will adopt.
