vLLM: servindo LLMs no Linux com alta vazão — história, instalação e primeiros passos

vLLM: serving LLMs on Linux with high throughput — history, installation, and first steps

If you have run a local LLM with Ollama or llama.cpp, you know it works very well — for one or two people. When demand becomes an API that must handle dozens of simultaneous requests, the situation changes: the GPU sits idle waiting, memory becomes fragmented, and throughput plummets. That is precisely the problem … Read more

A história da NVIDIA

The history of NVIDIA

In 1993, three engineers met at a Denny’s restaurant in California to found a graphics chip company in a market that already had dozens of competitors. Thirty years later, that company would become, at several points, the most valuable on the planet. This is the history of NVIDIA: from the flops that almost killed it … Read more

A história da AMD

The History of AMD

No technology company has died and been reborn as many times as AMD. Founded in 1969 to live in Intel’s shadow, it spent five decades alternating strokes of genius (Athlon, x86-64, Zen) with trips to the edge of the abyss — until an engineer named Lisa Su turned a US$ 2 stock into the largest … Read more

AMD vence a Nvidia em todas as especificações — e mesmo assim perde

AMD beats Nvidia on every specification — and still loses

Video summary: this article is a detailed summary of “AMD Beats Nvidia On Every Spec And Still Loses” from The Stack. Video URL: https://www.youtube.com/watch?v=bOHhUVSDmrw On paper, there should not even be a contest: the AMD MI300X accelerator carries 192 GB of memory against 80 GB on the Nvidia H100 and moves 5.3 TB/s of bandwidth … Read more

Google TPUs: arquitetura, gerações e modelos

Google TPUs: architecture, generations, and models

Around 2013, Google ran the calculation that alarmed Mountain View: if every Android user used Search’s voice commands for three minutes a day on x86 CPUs, the company would have to double its data centers just for inference. Consumer GPUs were still adapted gaming cards. The answer was … Read more

Servidor de IA recondicionado com 64 GB de VRAM

Refurbished AI server with 64 GB of VRAM

VRAM determines the model. Dense Qwen 27B–32B, quantized Llama 70B, Mixtral 8×7B — these require 32 to 64 GB, not the 24 GB of a 4090. Engineer Donato Capitella, with Bargain Hardware, built a refurbished Supermicro with four data center GPUs (64 GB total) for around £2,000 and benchmarked V100, P100 … Read more

Como funcionam as placas de vídeo

How graphics cards work

How many calculations does a graphics card perform per second to draw a Cyberpunk frame or train a network? Branch Education took apart an RTX 3090 — literally — and reconstructed the GA102 die in 3D. This article follows the video How do Graphics Cards Work? Exploring GPU Architecture. The generation … Read more

GPU vs TPU: como os chips de IA funcionam

GPU vs TPU: how AI chips work

Behind every ChatGPT token, every Sora frame, and every LLM you run in Ollama, an accelerator performs the same calculation trillions of times: matrix multiplication. The two ways to do this in silicon — GPU (NVIDIA) and TPU (Google) — start from opposing philosophies. This article … Read more
