The GTX 1660 Super is a light refresh: Like the GTX 1660 it replaces, it’s a 1,408 CUDA core card, with a base clock of 1,530MHz and a boost clock of 1,785MHz. In fact, every spec NVIDIA released is identical, until you get to the memory.
The GTX 1660 Super still has 6GB of video memory — enough for a card of its class — but it’s GDDR6, rather than GDDR5, and it data rate is 14Gbps, rather than 8Gbps. This increases memory bandwidth from 192 GB/sec to 336 GB/sec, which is actually higher than the GTX 1660 Ti, and on par with the original RTX 2060.
This increase in bandwidth is significant, but it’s difficult to say how much of an impact it will have on gaming and productivity tasks. While the RTX Supers had major differences like increased core counts and clock speeds, NVIDIA suggests the RAM changes alone here will provide a similar uplift. One chart it provided suggests a 10-20 percent increase over the GTX 1660 could be achievable. We’ll hopefully be able to verify those performance claims ourselves soon.
While the GTX 1660 Super is best described as a gentle revision, the same can’t be said of the GTX 1650 Super. In fact, it looks like that card is going to offer the biggest Super upgrade to date.
The GTX 1650 Super bests its predecessor in every way. It offers 43-percent more CUDA cores at 1,280, with a base clock of 1,530MHz and a boost clock of 1,725MHz, compared to the original’s 1,485MHz base and 1,665MHz boost. The card’s 4GB of RAM remains, but has been upgraded to GDDR6 at 12 Gbps, bringing the total memory bandwidth up to 192 GB/s, a 50-percent increase over the original. These improvements come with the requisite uptick in power consumption: The new card is referred to as having a TGP (“total graphics power”) of 100W, up from 75W, and NVIDIA says the GTX 1650 Super would ideally be paired with a 350W power supply, as opposed to the prior 300W recommendation.
These changes are bizarrely huge: The GTX 1650, a GPU capable of 3 TFLOPs, is being supplanted by a 4.4-TFLOP Super card. That’s a more significant difference than between the GTX 1660 and the GTX 1660 Ti, let alone any of the Super models.
NVIDIA’s press release claims that “the pair [of new Super cards] deliver up to 2X the performance of the prior generation GTX 10-series GPUs and up to 50-percent more performance over the original GTX 16-series.” It’s likely that both of these comparisons relate to the GTX 1650 Super: It has roughly two times the power of the last-generation GTX 1050 and roughly 50-percent more power than the GTX 1650.
On the face of it, the GTX 1650 Super is an exciting upgrade. It’s a cheap “1080p card” that’s likely to surpass the GTX 1060’s performance in many games, a comparison that will only improve as games are increasingly optimized for the more-modern “Turing” architecture the 16 series shares with pricier RTX GPUs. However, it’s bewildering that NVIDIA is lumping it in with the GTX 1660 Super, which has only seen a memory upgrade over the GTX 1660. You could wave the company’s branding decision away as a desire for consistency, but if there was ever a GPU that deserved the “Ti” branding, the GTX 1650 Super is it. Marketing these two very different Super cards in the same fashion is just confusing.
The GTX 1660 Super is available today from $229, a $10 increase over the original. The GTX 1650 Super will go on sale November 22nd with pricing to be confirmed before launch. In a world where you can find an (admittedly power-hungry and increasingly dated) AMD RX 580 for $180, NVIDIA needs to be aggressive on price if it wants to really put the squeeze on its rival.
