Currently, GDDR6X is the fastest graphics memory and delivers ultra-high bandwidth, which is close to that of HBM2 memory. GDDR6X is the successor of GDDR6 memory with significant improvements in all departments that include speed, bandwidth, and power efficiency. GDDR6X memory can have speed up to 21Gbps and can deliver bandwidth up to 1TB/s. The memory uses PAM4 signaling technology to achieve much higher speeds. It is developed by Micron and is currently being used in the latest top-end RTX 30 series graphics cards that include the RTX 3080/3090.
3070 and below all use GDDR6 only.
Something else to consider, along with having a true PCIe 4.0 slot
Highly doubt PCI 4.0 will have any impact on this generation, I dont consider the 3090 a realistic option from price perspective (prefer put that cash towards a decent monitor or something that will last 5-10 years).
Fairly big deal feature if true, essentially allows you to do PCI/GPU passthrough between host and VM without a secondary GPU (well thats my usecase anyway). In the past NVIDIA have intentionally crippled this kind of functionality so in usual fashion they can put it behind a paywall, looks like they might just allow this functionality on the 3000 series.
Remains to see if leveraging their RTX IO to boost loading speeds has any impact on the relevance of the PCI-E gen
The preview won't be available to developers until some time next year, which imo puts the first titles using it for a 2022 release at best. It won't make one bit of difference during Ampere's lifetime, especially since we all know how quickly developers adopt these new technologies in general.
I don't know, I haven't really done much reading about the new compression stuff and how much of the CPU's processing power is used to decompress data (I take it the data is textures, geometry etc.?).
Probably also general-purpose compression for other content. Most likely new compression algorithms will also come out of this, which were deemed prohibitive until now.
AMD cards have always had like double the VRAM compared to Nvidia counterparts, but Radeon VII is not gaming card only, its defect Radeon Instinct card with normal drivers and display outputs. If you think you need that 24GB for gaming, especially for 1080p/1440p just go ahead and buy it, sick of this retarded VRAM fight
Signature/Avatar nuking: none (can be changed in your profile)
