ENIAC has 50% more than EDVAC: $ 17,500 + 0.5 \times 17,500 = 17,500 + 8,750 = 26,250 $.

["ENIAC’s Monumental Impact: How This Pioneer Outperformed EDVAC by 50%", "In the early days of modern computing, two machines—ENIAC and EDVAC—stand as foundational milestones shaping the digital revolution. While both were groundbreaking, a lesser-known but powerful comparison reveals just how influential ENIAC was: with an original cost of $17,500, ENIAC was 50% more expensive than EDVAC, totaling $26,250 when accounting for 50% greater expense. This financial edge underscores not only ENIAC’s advanced capabilities but also its pivotal role in defining the scale and ambition of early computer engineering.", "### ENIAC vs. EDVAC: A Cost Comparison That Reflects Innovation", "To understand the magnitude of ENIAC’s performance, consider the simple math:\n[\n\ ext{ENIAC Cost} = 17,500 + 0.5 \ imes 17,500 = 26,250\n]\nThis equation shows that ENIAC’s price was 1.5 times that of EDVAC (where $17,500 is the EDVAC cost and $8,750 is half of it). This 50% premium reflects ENIAC’s superior processing power, speed, and versatility. As the first general-purpose electronic digital computer, ENIAC introduced capabilities unimaginable in the mid-1940s—capable of performing thousands of calculations per second, far surpassing its predecessors and even contemporaries like EDVAC.", "### Why ENIAC Outcomputed EDVAC by 50%", "ENIAC (Electronic Numerical Integrator and Computer) was designed primarily to calculate artillery firing tables for the U.S. Army, demanding unprecedented speed and accuracy. Its architecture, built with over 17,500 vacuum tubes, allowed rapid parallel processing—a radical leap from mechanical systems. Meanwhile, EDVAC (Electronic Discrete Variable Automatic Computer), though revolutionary in concept (introducing stored-program architecture), had a lower initial cost, signaling earlier development stages and less mature engineering.", "The cost disparity isn’t just fiscal—it’s a reflection of technological leapfrogging. ENIAC’s robust componentry and scale meant engineers invested heavily in reliability and performance, qualities crucial for military and scientific applications. EDVAC’s lower price indicated a platform still evolving toward full maturity.", "### Legacy Beyond the Numbers", "Though ENIAC’s price tag dwarfed EDVAC’s, the true legacy lies in scope: ENIAC represented a giant leap from mechanical calculation to true electronic computing, capable of tackling complex, real-world problems far beyond EDVAC’s original use case. That $8,750 premium symbolizes not mere expense, but a leap into the future—establishing trends in software, hardware design, and computational thinking that endure to this day.", "### Conclusion", "Environmentally and financially pronounced, ENIAC was more than 50% more expensive than EDVAC—a testament to how innovation and ambition shape technological progress. With a cost of $26,250, ENIAC wasn’t just a computer; it was a statement: computing could be fast, powerful, and transformative. Today, its impact ripples through every digital device, reminding us that breakthroughs often come with a significant (but justified) charge.", "Explore how ENIAC transformed technology and accelerated the digital age—proof that sometimes, going further means spending a little more to achieve greatness."]
