How many SPARCs is too many SPARCs? Posted on 2025-08-20 Contents Background I was browsing /r/vintagecomputing, as you do, and I came across this post: Hi all. Back in the day I was a developer working exclusively on Solaris. About 25 years ago, for one reason and another I came into possession of about 30 assorted SPARC based workstations and a few other bits and bobs, network/SCSI cards, keyboards, mice, etc. I think there's also one UltraSPARC in there too. This stuff was well past its

Powerful GPUs or Fast Interconnects: Analyzing Relational Workloads

news.ycombinator.com Unknown 2025-10-19 01:48:51

Authors: Marko Kabić, Bowen Wu, Jonas Dann, Gustavo Alonso Abstract In this study we explore the impact of different combinations of GPU models (RTX3090, A100, H100, GraceHoppers - GH200) and interconnects (PCIe 3.0, PCIe 4.0, PCIe 5.0, and NVLink 4.0) on various relational data analytics workloads (TPC-H, H2O-G, ClickBench). We present MaxBench, a comprehensive framework designed for benchmarking, profiling, and modeling these workloads on GPUs. Beyond delivering detailed performance metrics,

Building A16Z's Personal AI Workstation

news.ycombinator.com Marco Mascorro 2025-10-31 05:03:13

In the era of foundation models, multimodal AI, LLMs, and ever-larger datasets, access to raw compute is still one of the biggest bottlenecks for researchers, founders, developers, and engineers. While the cloud offers scalability, building a personal AI Workstation delivers complete control over your environment, latency reduction, custom configurations and setups, and the privacy of running all workloads locally. This post covers our version of a four-GPU workstation powered by the new NVIDIA

PCIe 8.0 announced by the PCI-Sig will double throughput again

news.ycombinator.com Cliff Robinson 2025-11-14 20:41:36

The PCI-SIG announced this week that it is not going to stop. Targeting a 2028 release, the PCIe 8.0 specification will double the throughput over PCIe 7.0. With the release, the PCI-SIG also shared two neat charts. PCIe Gen8 Announced by the PCI-SIG Will Double Throughput Again The PCI-SIG has this graphic to show what is happening to I/O bandwidth. It says that the I/O bandwidth is doubling every three years. Something to also keep in mind is that this is very device and interface centric.

The Best-Worst 8GB GPU of 2025

techspot.com Steven Walton 2025-12-07 22:25:00

Over the past few months, we've spent a lot of time testing the new 8GB graphics cards from AMD and Nvidia, and we've found them to be quite disappointing. There are countless examples where the 16GB versions deliver playable performance – sometimes even high refresh rate performance – while the 8GB models range from significantly slower to completely broken. While it's true that in all the examples we've shown so far, you can lower visual settings to get the 8GB models working, that's not an i

Nvidia RTX 5060 Ti 8GB vs. 16GB Tested Across PCIe 3.0, 4.0 and 5.0

techspot.com Steven Walton 2026-02-16 06:36:00

Recently we examined how PCI Express bandwidth influences the performance of the 8 GB Radeon RX 9060 XT when local video memory (VRAM) is exceeded. The entire purpose of that testing was to push past the VRAM limit, which, unfortunately for 8 GB graphics cards, is a relatively easy task in 2025. This can happen even when using settings that would otherwise be highly playable, as demonstrated by the 16 GB model. This is an interesting test for several reasons, the most notable being that PCIe ba

AMD Radeon RX 9060 XT PCIe Benchmark: 8GB vs. 16GB

techspot.com Steven Walton 2026-03-06 00:26:00

On store shelves, AMD's Radeon RX 9060 XT looks like a compelling option for gamers. It's affordable, backed by a trusted brand, and appears well-equipped for modern gaming. But there's a catch: the 8GB version is severely constrained by its limited video memory – a technical bottleneck that may not show up in standard benchmarks. That missing memory turns the 8GB model into a ticking time bomb for gamers hoping to future-proof their rigs. The 8GB RX 9060 XT is marketed under the same name as t

PCIe 7.0 is coming, but not soon, and not for you

theverge.com Jess Weatherbed 2026-03-16 14:22:06

The PCIe 7.0 specification has now been released, while many of us are still waiting for PCIe 6.0 to materialize in consumer products. The PCI Special Interest Group (PCI-SIG) announced on Wednesday that PCIe 7.0 is now available to members of its organization, delivering a theoretical maximum bandwidth speed of 512GB per second in both directions, across a x16 connection. “PCIe technology has served as the high-bandwidth, low-latency IO interconnect of choice for over two decades and we are pl

How much power can a PCIe x16 graphics card draw from the motherboard alone?

techspot.com Unknown 2026-03-18 23:01:00

Choose wisely! The correct answer, the explanation, and an intriguing story await. Correct Answer: 75W What was Comdex before it was shut down in the early 2000s? When installed in a motherboard's PCIe x16 slot, a graphics card such as the GeForce RTX 5080 can draw up to 75 watts of power directly from the slot. This power comes from the motherboard's +3.3V and +12V rails (3.3V × 3A + 12V × 5.5A), which is the maximum defined by the PCI Express base specification for a x16 slot (this limit ha
